Note: Preliminary screening by headspace analysis (Method 5021) or hexadecane extraction (Method 3820) is appropriate for samples that may contain high concentrations.

    10.1.4     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.

10.1.4.1     Scope
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     Ethyl methacrylate
    Acetonitrile     2-Hexanone
    Acrolein     2-Hydroxypropionitrile
    Acrylonitrile     Isobutyl alcohol
    Allyl alcohol     Light alkanes (e.g. as in petrol)
    2-Butanone (MEK)    Malononitrile
    t-Butyl alcohol     Methacrylonitrile
    Carbon disulfide    Methyl methacrylate
    Chloral hydrate     4-Methyl-2-pentanone (MIBK)
    bis-(2-Chloroethyl) sulphide   2-Picoline
    2-Chloroethyl vinyl ether   Propargyl alcohol
    1,2:3,4-Diepoxybutane    b-Propiolactone
    Diethyl ether     Propionitrile
    1,4-Dioxane     n-Propylamine
    Ethanol     Pyridine
    Ethylene oxide     Vinyl acetate

10.1.4.2     Sample extraction
Low concentration (<200 μg /kg, for individual compounds):
    * 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 (≥200 μg/kg, individual compounds):
    * methanol extraction followed by purge and trap technique.

10.1.4.3     Sample clean-up
Not applicable.

10.1.4.4     Sample analysis
The table below lists the specified US EPA SW-846 method.
