11.3.3 Sample analysis
The table below lists the US EPA SW-846 methods specified for volatile halogenated
compounds.
8021B
GC/ELCD
(P) 8260B GC/MS
Note: Preliminary screening by headspace analysis (Method 5035) or hexadecane extraction
(Method 8021B) is appropriate for samples which may contain high concentrations.
11.4 Miscellaneous volatile organic compounds
The following volatile compounds do not fall into the aromatic or chlorinated categories
detailed in the sections above, and may be analysed using the methods below.
Analysis of other volatile organics by these methods is not precluded. These methods could also
be appropriate for volatile petroleum products (hydrocarbon fuels and solvents).
Acetone
Acetonitrile
Acrolein
Acrylonitrile
Allyl alcohol
2-Butanone (MEK)
t-Butyl alcohol
Carbon disulfide
Chloral hydrate
bis-(2-Chloroethyl) sulphide
2-Chloroethyl vinyl ether
1,2:3,4-Diepoxybutane
Diethyl ether
1,4-Dioxane
Ethanol
Ethylene oxide
11.4.1 Sample extraction
Ethyl methacrylate
2-Hexanone
2-Hydroxypropionitrile
Isobutyl alcohol
Light alkanes (e.g. as in petrol)
Malononitrile
Methacrylonitrile
Methyl methacrylate
4-Methyl-2-pentanone (MIBK)
2-Picoline
Propargyl alcohol
b-Propiolactone
Propionitrile
n-Propylamine
Pyridine
Vinyl acetate
Low concentration (individual compounds < 200μg /kg):
• purge and trap technique (Method 5035)
• analysts should determine an appropriate concentration limit and ensure that results are
based on sample concentrations that do not exceed the instrumental range.
High concentration (individual compounds ≥ 200 μg/kg):
• methanol extraction followed by purge and trap technique.
11.4.2 Sample clean-up
Not applicable.
