Introduction 

Synthetic organic chemicals made their agricultural debut in the 1930’s when the compound 2-methyl-4,6-dinitrophenol (DNOC) was used for weed 

control. The first patent was issued for a dithiocarbamate fungicide by Robert Zimdahl in 1978. 15 However, widespread use of pesticides began in 1939 when 

the insecticidal properties of DDT were discovered and used during World War II. 14 In 1944, it was proposed that DDT be used to eradicate malaria after 

successfully protecting soldiers from mosquitoes that spread the disease. From 1945 to 1948, after spraying half a million pounds over 135,000 miles of Italy, 

the malarial death in that country was reduced to zero. 11 

Although there is no singular event that raised the public’s awareness of the dangers and risks of DDT, in 1962 an American biologist wrote Silent Spring, 

which had a significant impact. The book describes the long-term effects that synthetic chemicals have on the environment, people’s ambivalence toward using 

pesticides for pest control, and the risks these chemicals pose to the health of animals and humans. 2 The public outcry that resulted from the book led to 

international regulations restricting the manufacture, use, and residue of pesticides in feed and food, as well as emission into the environment. Despite the 

regulations, however, synthetic pesticides continue to be used for pest control in the agriculture industry all over the world. 

As the human population increases, so does the need for more and more food. Eventually, demand will exceed supply and, in order to sustain ourselves, food 

will become a global commodity. As a result, synthetic pesticides have evolved from being generically used for the chlorination of hydrocarbon bulk material 

into the specific purpose of eradicating and degrading pests. Decades ago, pesticides were applied in high concentrations of active ingredient per hectare, but 

today we can get the same or better results from a few grams. From an analytical perspective, the apolar lipophilic pesticides have gradually been replaced by 

more polar compounds with specific activity resulting in the very wide range of active compounds of different chemical nature – a true challenge for residue 

analysis. 

Because of the high agricultural demand for pesticides, coupled with regulatory pressure, a broad array of synthetic chemicals now exists in the environment. 

As a consequence, the food safety and environmental analysis of pesticides must keep pace with the ever-increasing demand for the analysis of highly complex 

mixtures of active compounds and byproducts. The need to quantify pesticides at trace concentrations in difficult matrices requires highly developed analysis 

concepts that provide increased selectivity, sensitivity and bandwidth to detect and quantify such a large number of compounds. International pesticide 

regulations cover several hundred pesticides, including more than a thousand regulated active components for food and feed. Pesticide databases have 

compiled a record number of more than 1,800 compounds that are potentially a subject for analysis. 5 In the United States, California has 925 registered 

pesticide active ingredients that are marketed by 11,947 individual products. 14 


Introduction 

Modern analytical methods cover gas and liquid chromatography separation of extracts typically with mass spectrometry detection. The use of classical 

detectors like ultra-violet (UV), electron capture detector (ECD) or nitrogen phosphorus detector (NPD) has been declined by the need for increased 

selectivity in multicomponent methods and inherent confirmation. 

The European Council Directive 96/23/EC, which describes the performance of analytical methods and the interpretation of results, is requesting 

performance criteria with required minimum required performance levels (MRPL) for screening and confirmation methods. The Directive grants 

identification points to analytical methods using chromatography with mass spectrometric detection for the determination of organic residues or 

contaminants. For the confirmation of substances listed in Group A of Annex I in Directive 96/23/EC, a minimum of four identification points are required. 4

About This Manual 

Analytical methods for food safety are used to screen and confirm positive pesticides results and they must be granted at least four identification points. For 

LC/MS and GC/MS detection methods using either electron ionization (EI) or chemical ionization (CI), two derivatives or the powerful MSMS or HRMS 

are available. For maximum productivity, the highly specific MSMS and HRMS methods are the preferred methods. Multi-residue pesticide methods are 

analytically challenging because of the diverse number of chemical structures and physical properties of the target analytes. 

Thermo Fisher Scientific provides methods and mass spectrometry instrumentation that complies with the strict international rules for screening and 

confirmatory analyses on either LC or GC separation for polar or less polar compounds using ion trap, triple quad or high resolution accurate mass MS 

instrumentation. The information and methodology in this document will show you how to analyze large numbers of pesticides using the TSQ Quantum GC 

mass spectrometer. 


Pesticide analysis is a chromatographic challenge because there is a large variety of chemical compound groups that require high sample throughput and short 

run times. Sample preparation and clean-up is an integral step in pesticide analysis because there is a significant amount of sample matrix involved. Setting up 

the analytical method in a particular way can cut down on instrument maintenance and increase the robustness of the method. In this manual, we will 

describe how to set up a generic method for the multi-component GC-MS/MS analysis of over 500 pesticides. 

This method includes information about implementing the widely distributed QuEChERS sample preparation procedure, which is suitable for non- and 

low-fat sample material and can be employed for GCMS and LCMS. For GCMS extractions, an additional solvent exchange step is included in the method, 

which provides the extract in a GC-compatible solvent. For LCMS, the intermediate acetonitrile extract can be used directly. 

The GCMS method of choice for a multi-component pesticide analysis in matrix samples is the MS/MS technique using either ion trap or triple quadrupole 

mass spectrometers. The sample preparation, GC configuration and analytical method setup information is valid for ion trap detection with PolarisQ or ITQ. 

The MS part of this manual focuses on the use of the TSQ Quantum GC triple quadrupole mass spectrometer for creating a multiple reaction monitoring 

(MRM) analysis method. 



This manual also describes the recommended GC configuration with either split/splitless (SSL) or the temperature programmed inlet (PTV). For increased 

method robustness and easier maintenance, we recommend the use of a pre-column for matrix samples. The GC and autosampler analytical method 

parameters are provided with the analytical column of choice. The analytical method is described in detail for easy implementation. For easy setup of the 

pesticide method, a dedicated start-up kit is recommended. High sample throughput applications will require additional GC consumables. 

The TSQ Quantum GC mass spectrometer is operated in H-SRM mode, which provides the required high selectivity for a multi-component pesticide 

method. The SRM acquisition parameters for all pesticides are provided in the required precision with two digits prepared for exploiting the high H-SRM 

matrix selectivity. All pesticides are listed with precursor and product ions, as well as collision energy. All given transitions have been proven in Thermo 

Scientific application labs for use with different matrices. At least two independent SRM transitions are listed for each pesticide and they are compliant with 

international regulations and for reaching highest ranking with the European identification point system. 

Several pesticide compounds are listed with more than two SRM transitions. This flexibility in data acquisition allows for additional result confirmation and 

verification with unexpected matrix interferences of unknown sample matrices. 

QuanLab Forms is a workflow software suite for manual and full automatic data processing. peak integration, calibration and quantitation, QA/QC with 

qualifier checks and reporting provide a seamless data analysis for the multi component pesticide method. A special feature in QuanLab Forms data processing 

(called a local method) offers easy checking and optimization. 


What is a Pesticide? 


In the simplest terms, the U.S. Environmental Protection Agency (EPA) defines pesticides 13 as agents employed by humans to destroy or control pests. A 

pesticide can also be defined as a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or a device used against any pest. 

Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, 

destroy property, spread or are a vector for disease, or cause a nuisance. 

Pesticides and Food 

Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and animals. There is great concern that 

using pesticides on food crops is dangerous to people who consume those foods. The United Nations Codex Alimentarius Commission has recommended 

international standards for Maximum Residue Limits (MRLs) for individual pesticides in food. 3 

In the European Union (EU), the maximum residue levels (MRLs) are set by the Directorate General for 'Health and Consumers' (DG-SANCO). In the 

U.S., the EPA requires that the amount of residue on food is lower than the tolerance level to be considered safe. The EPA bases the tolerance level on the 

toxicity of the pesticide and its breakdown products, the amount and frequency at which the pesticide is applied, and the amount of pesticide residue that 

remains in or on food by the time it is marketed and prepared. Tolerance levels are obtained using scientific risk assessments that pesticide manufacturers are 

required to produce by conducting toxicological studies, exposure modeling, and residue studies before a particular pesticide can be registered. 



Pesticide Chemical Classes 

There are many chemical classifications of pesticides: 

• Algicides or algaecides for the control of algae 

• Avicides for the control of birds 

• Bactericides for the control of bacteria 

• Fungicides for the control of fungi and oomycetes 

• Herbicides for the control of weeds 

• Insecticides for the control of insects, which can be ovicides (substances that kill eggs), larvicides (substances that kill larvae) or adulticides (substances that 

kill adults) 

• Miticides or acaricides for the control of mites 

• Molluscicides for the control of slugs and snails 

• Nematicides for the control of nematodes 

• Rodenticides for the control of rodents 

• Virucides for the control of viruses (e.g. H5N1) 

For an overview of compound classes, visit the Compendium of Pesticide Common Names website 5 , the Pesticide Action Network (PAN) Pesticide 

Database 9 , or similar websites for detail compound information.

Preparing Samples 


The sample preparation and clean-up process for pesticide analysis has not been standardized. Typically, the procedures are optimized for different matrices 

and mirror the individual experience and knowledge of many trace chemical laboratories. It has been shown that many methods are equivalent and do not 

exhibit significant weaknesses, which especially applies to the widely used GPC clean-up 8 or the very popular QuEChERS (Quick, Easy, Cheap, Effective, 

Rugged and Safe) method developed by Anastassiades. 1 The selection of injector, column, and detector type has a major impact on the overall performance of 

a method. More importantly, these selections may also affect whether or not the required recovery limits of 70-110% as a mandatory quality control parameter 

set by the European DG-SANCO13 will be met. 6 

The determination of pesticides in fruits and vegetables has been simplified by using a QuEChERS method and the findings were recently published as 

AOAC Method 2007.01. The sample preparation is simplified by using a single-step buffered acetonitrile (MeCN) extraction and liquid-liquid partitioning 

from water in the sample by salting it out with sodium acetate and magnesium sulfate (MgSO 4 ). 10 

Sample preparation involves careful homogenization of the sample. Extraction solvents must be buffered and the powdered reagents measured at appropriate 

amounts for the size of the prepared sample. Some reagents cause an exothermic reaction when mixed with water, which can adversely affect the recovery of 

target compounds. The recommended consumables required for sample preparation and analysis were rigorously tested. See Table 3 for a list of consumables 

that are used in this method extraction procedure. 

A QuEChERS extraction procedure is recommended because it provides good recovery for a wide range of compounds in many different matrices.

QuEChERS Flowchart 



Extracting Samples and Cleaning Up 

When using the QuEChERS method to prepare samples, you must perform an extraction and clean up the sample. The next step is to exchange solvents and 

produce a final solvent that is more amenable to a splitless injection. 10 

To perform an extraction: 

1. Weigh a thoroughly homogenized 15 g sample into an extraction tube. 

2. Pour 15 mL of 1% glacial acetic acid/MeCN extraction solvent into the tube on top of the sample. 



3. Cap the tube and vortex it for 30 seconds. 

4. Remove the cap and pour the powder reagents poured slowly into the MeCN layer. Tighten the cap securely on the 50 mL extraction tube and vortex for 

30 seconds until all of the powder reagents are mixed with the liquid layers. 



5. Place the tube on a mechanical shaker for 5 minutes and centrifuge it for 5 minutes at 3000 rpm. 

6. Remove 11 mL of the top MeCN layer and transfer it to a 15 mL clean-up tube. 



7. Cap the tube, vortex it for 30 seconds, and then centrifuge it for 5 minutes at 3000 rpm. 

8. Transfer a 5 mL aliquot of the top layer into a clean test tube for solvent exchange. 



Exchanging Solvents 

To exchange solvents: 

1. Evaporate a 5 mL aliquot of cleaned up extract to dryness under a gentle stream of nitrogen at 40 °C (about one hour). 

2. Immediately remove the tube to prevent over-drying. 



3. Add 900 μL aliquot of hexane/acetone (9:1) and spike 100 μL of the internal standard, d10-parathion, into the organic solution. Cap the tube and vortex 

it for 15 seconds. 

4. Transfer 1 mL of extract to a 2 mL clean-up tube, cap it tightly, and vortex for 30 seconds. 



5. Centrifuge the extract for 5 minutes at 3000 rpm and then transfer 200 μL of the light green clear extract to an autosampler vial with a small glass insert 

for injection. Spike the individual calibration levels into each extract for the calibration curve in matrix. See Figure 1 for more QUeChERS information.

Setting Up a Method 


To set up your instrument method for pesticide analysis: 

1. Run the instrument in full-scan mode for the compounds you want to analyze. 

2. Download the SRM Transition.xls file from the Pesticide Analyzer Reference CD. The Xcalibur software uses this file to import transitions into your 

instrument method. 

3. Open the SRM Transitions.xls file in Microsoft Excel and customize it as follows: 

a. Delete the compounds you do not need. 

b. Add the start and stop times based on the retention times from the full scan run. 

c. Delete the header from the file. 

4. Save the file in .csv format. 

5. Open Xcalibur and click the Instrument Setup icon. 

6. Click the TSQ Quantum icon in the left pane. 

7. Select TSQ | EZ Method from the main menu and click the Import List button. 

8. Browse to the .csv file on your computer and select it. 



9. Now you can run your standards and verify that you can view all your compounds. 

10. Xcalibur will organize the compounds by parent mass (low to high). 

11. Now you can run your standards and verify that you can view all your compounds. 


Configuring the GC/MS System for Pesticide Analysis 


The analytical setup and method parameters in this document describe the basic setup for the quantitative analysis of pesticides using the TSQ Quantum GC 

mass spectrometer, TRACE GC Ultra gas chromatograph, and TriPlus autosampler. The method parameters have been selected to balance the analytical 

requirements for a large number of pesticides covering a wide range of volatility, chemical and chromatographic characteristics. 

Analyzing limited subsets of pesticides only with partial optimization for specific compound classes will improve separation and allow you to analyze faster. 

Customize the method template to include the particular compounds you are specifically looking for. 

The use of consumable components, such as insert liners, pre-columns and analytical column, has been tested by Thermo Fisher Scientific application 

laboratories for optimum analytical performance and sample throughput. 

TRACE GC Ultra 

The TRACE GC Ultra can be configured for Split/Splitless (SSL) or Programmable Temperature Vaporizing (PTV) injection techniques. The SSL injector 

can be used to analyze pesticide compounds in very low concentrations and for relatively dirty matrices. The PTV injector, however, allows you to vary the 

injection volume and temperature, which can lower detection limits and better analyze thermally sensitive compounds. 



PTV Injector 

There are two types of PTV injectors that can be used for pesticide analysis: 

• The Brightly Enhanced Sample Transfer (BEST) PTV injector contains very low thermal mass components and can achieve very fast heating and cooling 

rates. This type of PTV injector maintains unprecedented sample integrity using the specially designed inert liners and the long vaporizing chamber with 

reduced internal diameter. It can provide a virtual discrimination-free sample transfer in any situation, even when using high boiling-point samples. The 

PTV injector’s compatibility with dirty samples makes it the ideal complement to the cold on-column injector. 

• The Large Volume BEST PTV injector has the same capabilities of the standard PTV injector, but it can accept larger injection volumes. This type of 

injector is compatible with dirty sample matrices. It is recommended for injection volumes > 10 μL, which can be injected all at once, while larger 

volumes can be programmed to inject slowly. 

Note The injection of larger solvent volumes strongly reduces the effect of active surfaces during the injection process, which is caused by the surrounding 

solvent vapor momentarily protecting the labile pesticide compounds. For example, when using Endrin breakdown as a tool for diagnosing issues with 

excessive injection port activity. Sample preparation time is greatly reduced by shortening the extract evaporation times. 

The use of a pre-column for matrix samples is recommended for pesticide analysis. Typically, a pre-column is an empty 0.53 mm inner diameter column 

of standard length, as determined by the type of injection volume. When injected, matrix samples are typically deposited in the insert liner and 

pre-column. The analytical column is protected from the entry of low volatile matrix components, which preserves the calibrated retention times and 

extends the life of the column. We recommend that you occasionally clean and maintain the injector, replace the insert liner, and replace the pre-column. 

Always use the appropriate mini-unions or a glass press-fit connector to connect the pre-column. Be aware that leaks can occur when using glass press-fit 

connectors with temperature programmed methods. 

For increased efficiency when injecting samples, you can upgrade the TRACE GC Ultra with a PTV backflush system, which eliminates the irrelevant parts of 

a dirty sample during the cleaning phase. Depending on your injection volume preference, there are two types of backflush systems available: 



• The BEST PTV Backflush upgrade option for injection volumes < 10 μL inverts the direction of the carrier gas flow in the PTV inlet to vent dirty 

matrices and high boilers from the split line. This feature prevents these compounds from entering the analytical column, which significantly reduces 

analysis time and extends the life of the column. This option includes a 2 m pre-column. 

• For injection volumes greater than 10 μL, the Large Volume Backflush upgrade option allows you to enhance PTV injector performance. This option 

enables the solvent venting phase to occur through the backflush system, which allows for a significantly higher recovery of volatiles and makes it possible 

for you to increase the injected volume. This option can also be used to eliminate the high boiling part of the sample. Preventing large quantities of 

solvent from entering the analytical column and reaching the detector makes large volume PTV easily amenable to mass spectrometers. This option 

includes a 10 m pre-column. 

The injection parameters for PTV are described in the following tables. 



Table 4. 

PTV Injector Parameters 

Setting 

Parameter 

Mode 

PTV splitless (recommended). Also, an automated PTV on-column is possible. A cold injection guarantees virtually no 

compound breakdown and allows for injection volumes of more than 10 μL. 

Backflush optional with retention gap. Avoid glass wool in the liner because it gets active after few injections and causes a 

loss of certain compounds.

Setting 

Solvents Cyclo-hexane/Acetone 9:1 

Parameter 

• Beware of polar solvents that moisten the column film. 

• Do not use 100% acetone. 

• Acetonitrile (ACN) is not suitable for GC injection (only LC) because it strips the deactivation and damages 

the column film. 

• With QuEChERS sample preparation, solvent exchange is necessary, so small amounts of ACN in a suitable 

solvent are acceptable. 

• Alternative solvents are ethylacetate and ethylacetate/cyclohexane at 1:1 mix (or Ethyl Acetate/Cyclohexane 1:1)

SSL Injector 

There are two configurations of the SSL injector for pesticide analysis: 

• The Optimized Geometry SSL injector upgrade option is used for injecting 1-5 μL samples at a constant temperature. 

Note Labile pesticides, as indicated in the list of compound classes, cannot be analyzed at optimum performance. For analysis of those compounds, the 

B.E.S.T. PTV injector is recommended. 

• The Large Volume SSL injector upgrade option allows you to introduce volumes as high as 50 μL in a standard split-splitless injector. Using Concurrent 

Solvent Recondensation (CSR, a Thermo Fisher Scientific patented technology) enables you to overcome the limitations of the liner’s internal volume. 

The solvent vapors are recondensed in the pre-column and transferred to the analytical column. CSR large volume injection can be performed manually 

or automatically with the AI/AS 3000 II and TriPlus autosamplers. 

The injection parameters for SSL are described in the following table.

SRM Method Library 


For the quantitation and confirmation of pesticides by GC-MSMS, the acquisition mode of Selected Reaction Monitoring (SRM or MRM - multiple reaction 

monitoring) is used. With the TSQ Quantum GC mass spectrometer, our unique H-SRM (highly selective reaction monitoring) mode is available. Because of 

its highly resolved precursor ion selection, most of the accompanying matrix can be cut from the collision cell and very high signal-to-noise peak detection can 

be performed. 

The H-SRM mode of the TSQ Quantum GC mass spectrometer operates at optimum selectivity using precise precursor masses. For that purpose, all masses 

of precursors and product ions are listed in the table below with two decimals for unsurpassed matrix selectivity. Also in the table below, Exact Mass refers to 

the mass of the monoisotopic M and Mass Defect refers to the difference between the exact mass and nominal mass normalized to 100 Da. 

The collision energies are empirically determined values. Typically, low collision energies are preferred for generating a single intense product ion. In 

compliance with international regulations, two product-to-product ion transitions are used for quantitation and confirmation with the ion ratio. 

For many compounds, monitoring of more than two transitions is listed. This flexibility allows you to react to unexpected matrix interferences. The optimum 

transitions for a given matrix can be selected in QuanLab Forms data reprocessing software in the local processing method.
