General InformationPrinciples of OperationThe sample enters the Thermo Scientific Orion 2110XP ammonia analyzerand passes through the inlet valve, bypass/needle valve, inlet filter, pressureregulator, flow meter and into the restrictor tubing. The sample then passesthrough the flow cell manifold into a reagent bottle through a diffusiontubing assembly where pH adjustment takes place. The pH-adjusted samplethen flows back through the manifold into the flow cell as air is introducedfrom the air pump to ensure proper mixing and fast response. The samplethen flows into an atmospheric drain via the diverter valve.K E YFigure I-12110XP SchematicAnalyzerReference SolutionAir PumpElectricFluid PathFluid Restrictor TubingAir PathReference Solution PathReagent Overflow PathDiffusion Tubing1 2 3 4 5Power4-20mA OutputRestrictor TubingAir FilterCheckValveAir InletFlow MeterPressurizes Flow Cellto Initiate SiphoningSenseTEMPREFCalibrationPortSafety Drain forReagent OverflowCalibration LevelRegulatorValveMeasure LevelBypass / NeedleValve and FilterCalInlet ValveSampleValveFlow Cell BlockReagent ManifoldValve PositionsCalibration Mode - PUSHSample/Measure Mode - PULLDiffusion TubeReagentReagent BottleMain FeedDrainThermo Scientific Orion 2110XP Ammonia Analyzer User GuideI-3

General InformationThe sensing electrode responds logarithmically to changes in the ammoniaion concentration. This response is described by the Nernst equation:Where:E = E o + 2.3 (RT/nF) log (C/C iso )E = measured electrode potential, mVE o = potential, when C equals C iso , mVR = ideal gas constantT = temperature of sample, degrees KnF= valence of ionic species (+1 for ammonia ion)= Faraday’s constantC = effective ammonia ion concentration (activity)C iso = concentration (activity) of ammonia ion where potential E istemperature independent (isopotential point)The above equation indicates that the measured potential varies with bothtemperature and the concentration of the ion of the interest. In order toeliminate error caused by fluctuations in sample temperature, the 2110XPmicroprocessor constantly updates temperature corrections from datasupplied by the ATC probe.From the Nernst equation, the theoretical response of a ammonia ionselective electrode to a ten-fold change in concentration at 25 °C is59.16 mV. This is referred to as the electrode slope (S). Most electrodes,however, do not exhibit a theoretical slope. Therefore, the analyzer iscalibrated to determine its actual value. Two standards are used to provideinformation necessary for the microprocessor to compute the actual slopeand E 0 for use during sample analysis.In order to eliminate interference from hydrogen ions, which can becomesignificant when measuring low levels of ammonia, the 2110XP analyzeradjusts the sample pH. This pH adjustment is accomplished by thepatented passive-diffusion process wherein the sample passes througha length of tubing contained in the reagent bottle. The reagent diffusesthrough the tube wall and mixes with the sample, which adjusts the samplepH to below 4.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideI-4

General InformationPrinciples ofCalibrationDouble KnownAddition (DKA)Calibration procedures for analytical instruments are important and mustbe performed carefully. The calibration procedure used in the ThermoScientific Orion 2110XP is a variation of Double Known Addition (DKA)using advanced electrode and flow cell technology in combination with thepassive diffusion system. This method has the distinct advantages of beingfast, easy, and accurate.Before calibration begins, the diverter valve is pushed in to divert flow fromthe measure drain, allowing the flow cell to fill.At the beginning of the DKA calibration the actual concentration in thesample is unknown. The analyzer measures the potential (E s ) and storesthis value in the microprocessor. A known amount of standard 1 solutionis added to the flow cell, which increases the concentration (C s ) with acorresponding known amount (dC 1 ). During this process, air is pumpedinto the flow cell, thoroughly mixing sample and standard in a closedloopsystem. The new potential (E 1 ) is measured and stored automaticallywhen stability is reached. Adding standard 2, preferably 10 times moreconcentrated than standard 1, increases the concentration (dC 2 ) in thesample reservoir. Again, the new potential (E 2 ) is measured and storedwhen the reading is stable. Now, we have the following three unknowns:E s =E o + S(T s /298.15) log (C s /C iso )E 1 =E o + S(T 1 /298.15) log [(C s + dC 1 )/C iso ]E 2 =E o + S(T 2 /298.15) log [(C s + dC 1 + dC 2 )/C iso ]S is the Slope at 25 °C (298.15 K)T is the temperature in Kelvin, measured when the potential E is measured.Figure I-2Flow Cell Volume for DKAE s , E 1 , E 2 have been determined during the calibration procedure. Themicroprocessor solves these three equations, to obtain the values of Sand E o . The calibration result is stored for use during online monitoringto convert the measured potential and temperature in the sample intoconcentration values in either ppm or ppb.When the calibration is complete the flow cell drains as the sample flowreturns. The flow cell volume returns to the measurement level. Afterallowing approximately 30 minutes for concentrated calibration solutionto be flushed from the system, the 2110XP analyzer can begin samplemeasurement again.In addition to Double Known Addition (DKA), the 2110XP analyzer alsoallows the operator the ability to perform an offline calibration.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideI-5

General InformationOffline CalibrationThe offline calibration feature of the 2110XP analyzer allows the operatorto adjust the analyzer to values determined by alternate methods used intheir laboratory such as elemental spectroscopy and ion chromatography.The offline calibration is essentially a one point calibration. To perform anoffline calibration, a sample is taken from the bypass of the analyzer; thesample concentration value is stored in memory; the sample is analyzedby an alternate method of choice; the previously stored reading is adjustedto the lab method result; and the analyzer is then returned to the analysismode. The term “offline calibration” refers only to the fact that a samplefrom 2110XP analyzer bypass is taken “offline” for laboratory analysis; infact, no downtime is experienced during the procedure and the analyzerremains online throughout.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideI-6

Shake out as much of the fill solution as possible through the sidearm.Drain the fill solution through the sidearm or use a pipet or syringe.4. While passing the 1/8 inch tubing into electrode sidearm, slide the 1/4inch tubing over the sidearm. The outside tubing should extend 3/8 to1/2 inches over sidearm. Refer to Figure II-10.Figure II-10Reference Electrodewith Filling SolutionReference ElectrodeFilling SolutionGasketTubing Bottle AdaptorSmall 1/8” Tubing InsideBottle CapElectrode SidearmLarge 1/4” TubingCeramic Frit5. Remove the cap and fluid seal from reference electrode fill solutionbottle (Cat. No. 181073). Hold the bottle in an upright position.Check that the rubber gasket is properly aligned, and then connectthe cap end of the tubing assembly to the bottle. The 1/8 inch tubingshould extend into the bottle.6. Hold the reservoir bottle above the electrode with the bottle cap enddown. The electrode should be horizontal with the sidearm pointingup. Gently shake the electrode to allow any trapped air bubbles to riseinto the bottle as the electrode fills with solution.7. Dry off the ceramic frit on the base of the electrode with a lint-freewipe. Squeeze the bottle for a few seconds. A small amount of fillingsolution should bead up on the frit surface, indicating good fillingsolution flow. If no moisture is visible, the electrode is clogged andshould be cleaned or replaced.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideII-13

Analyzer Preparation8. Invert the electrolyte bottle and snap it into the clip. Refer to FigureII-11. Use the pushpin supplied with the reference electrode topuncture three air vents on the bottom of the filling solution bottle.Caution: Failure to vent the filling solution bottle will lead to noisyand drifting output signals.9. Plug the electrode cable marked “Reference” into the top of theelectrode, and tighten the screw cap. Be sure to push back the blackcap to verify a secure connection between the male and female pinconnection prior to tightening.10. Tighten the screw cap connection to the cable.Note: Do not twist the cable while tightening the connection. Twistingmay cause damage requiring premature replacement of the cable.11. Insert the reference electrode into its port in the flow cell cap.

Chapter IV CalibrationCalibration SetupThe Thermo Scientific Orion 2110XP ammonia analyzer provides simpleand fast calibration cycles using double known addition that quicklyhave your system back online with security and confidence. The 2110XPanalyzer monthly calibration is quick and accurate using a simple pipet toinject two known standards into the sample matrix.Prior to performing a calibration, refer to Chapter III, Use of the SetupMode for instructions on how to properly configure the 2110XP analyzer.The value of the calibration standards, volume of the calibration standards,and the volume of the flow cell must be entered in the setup mode.Adjust the flow cell volume according to the precise factory calibrationvolume that is printed on the side of each flow cell.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideIV-1

CalibrationFlow Cell OperationThe sample reservoir in the flow cell, as shown in Figure IV-1, has twosample volumes: a normal operation volume of 20 mL and a highlyaccurate and individually calibrated flow cell volume of approximately95 mL. The lower volume results in fast system response while online, andthe higher volume ensures accuracy in calibration.Figure IV-1REFTEMPSenseCalibration PortCalibration LevelMeasure LevelFlow Cell BlockRecommendationsWhen the Thermo Scientific Orion 2110XP ammonia analyzer is firstcommissioned, it is advisable to flush out fluidics system overnight priorto initial calibration and use. The electronics need not be turned on at thistime. Refer to Chapter IV, Rinsing the Flow Cell.• For accurate volume displacement install the ATC probe, ammoniasensing electrode and reference electrode in their respective flowcell cap ports. Refer to Chapter II, Installation of New AmmoniaElectrode, Chapter II, Installation of the ATC Probe and Chapter II,Installation of New Reference Electrode Reference.• Close the calibration port.• When rinsing the flow cell before a standard calibration, be sure torinse off the inside of the reservoir lid with deionized water to preventbuildup of ammonia contamination along the lid.• To ensure the analyzer achieves stability and minimize interferenceduring calibration, the operator should minimize activity on systemduring calibration.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideIV-2

CalibrationRinsing the Flow CellWarning: Be sure to follow the procedure for rinsing the flow cell.DCBA50403020101. Open the sample inlet valve, see A .• Position the valve with pointed end facing up for open position.2. Open the bypass/needle valve by turning it counterclockwise, see B .• Check for appropriate sample flow.• Adjust pressure regulator if required. See step 3.3. Adjust the knob on the pressure regulator, see C , so the ball in theflow meter indicates the correct flow rate reading, see D . The flowrate should be adjusted to 40 mL/minute.• Pull out the knob to unlock the setting and adjust the flow rate.• Turn the knob clockwise to increase the flow rate.• Turn the knob counterclockwise to decrease the flow rate.• Push in the knob to lock the setting.4. Push in the diverter valve on the flow cell.• Flow cell will begin to fill.5. Flush the flow cell for 10 to 60 minutes. The sample will drain fromthe siphon tube into the siphon drain to the waste.6.

CalibrationBefore Performing aDKA CalibrationMaximum system accuracy is ensured through a fast, easy and accuratecalibration performed in the expected sample range. This calibrationprocedure uses equipment supplied in the ammonia calibration kit(Cat. No. 2110XPCAL).Recommendations• Wait at least one hour to perform a calibration after changing thereagent or cleaning the electrode.• Check that the present sample concentration is equal or less thanstandard 1. If not, calibration can still be performed with a loss inaccuracy as long as the background concentration is not significantlylarger than the standard 1 concentration.• Proper pipet technique is crucial to the calibration. If the operator isnot familiar with pipet equipment or technique, refer to the Appendix,Pipet Operation section.• Do not touch the pipet tip with bare fingers. Risk of contamination ispossible. Use powder free gloves to prevent contamination.• When using a pipet to inject standards during calibration, use a freshpipet tip for each standard and each injection.• When a fresh tip is installed, rinse the tip with the same concentrationstandard as the intended injection.• Fill the tip and dispense the standard 1 to 3 times before injecting thestandard into the flow cell. Be sure to discard the standard in thedrain between the rinses.• Wipe any excess liquid from the outside of the tip without touchingthe opening.• Insert the pipet tip into the calibration port on the flow cell cap.Figure IV-4Pipet Dispensing• Be sure to hold the pipet completely vertical while dispensing. Donot inject the standard onto the side of the flow cell, as a film may beretained on the inside of the wall, resulting in calibration precisionerrors. Refer to Figure IV-4.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideIV-5

CalibrationPerforming aDKA Calibration• To begin a DKA calibration, the system starts from the measure mode.• The calibration port must be closed for proper flow cell pressure.• The value of the calibration standards, volume of the calibrationstandards, and the volume of the flow cell must be entered in the setupmode prior to performing a calibration.

AppendixPipet OperationTip EjectionTo help eliminate the risk of contamination, each pipet is fitted with a tipejector system. The tip ejector system consists of a soft-touch tip ejectorand specially designed gearing mechanism. To release the tip, point thepipet at suitable waste receptacle and press the tip ejector with your thumb.You can attach the pipet shelf hanger on a counter, pipet stand or anywherewhere you want to hang your pipet.Clean the area where you plan to attach the shelf hanger. Apply two stickersto the underside of the shelf hanger. Press the shelf hanger firmly into placeon a shelf, counter top or pipet stand. To use, hang the grippy finger rest onthe shelf hanger.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideA-11

AppendixPipet TechniquesGeneralSpecial care should be taken to avoid liquid being aspirated into the interiorworking of the pipet. Push and release the push button slowly at all times,particularly when working with high viscosity liquids. Never allow the pushbutton to snap back. Make sure that the tip is firmly attached to the tipcone. Check for foreign particles in the tip.• Do not touch pipet tip with bare fingers. Risk of contamination ispossible. Use powder free gloves for protection.Before you begin your actual pipeting work, fill and empty the tip 3 to5 times with the solution that you will be pipeting. Hold the pipet in anupright position while aspirating liquid. The grippy should rest on yourindex finger. Make sure that the tips, pipet and solution are at the sametemperature.Forward TechniqueFill a clean reagent reservoir with the liquid to be dispensed.1. Depress the push button to the first stop.2. Dip the tip under the surface of the liquid in the reservoir to a depthof about 1 cm and slowly release the push button. Withdraw the tipfrom the liquid, touching it against the edge of the reservoir to removeexcess liquid.3. Deliver the liquid by gently depressing the push button to the first stop.After a delay of about one second, continue to depress the push buttonall the way to the second stop. This action will empty the tip.4. Release the push button to the ready position. If necessary, change thetip and continue pipeting.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideA-12
