Method 8260B Solids

Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry (GC/MS)


Method 8260B is used to determine volatile organic compounds (VOC's)  in a variety of solid waste matrices.  This method is applicable to nearly all types of samples, regardless of water content.  Method 8260B can be used to quantitate most volatile organic compounds that have boiling points below 200°C.  Such compounds include low molecular weight halogenated hydrocarbons, aromatics, ketones, nitriles, acetates, acrylates, ethers, and sulfides.

Sample collection usually involves an EnCore® or equivalent sampler.  The device collects and stores the sample in an airtight sealing cap which eliminates loss of VOC's.  The sample should be collected in duplicate.  After sample collection, the sample can be introduced into the GC/MS using a variety of techniques.  Purge-and-trap, Method 5035, is the most commonly used technique.

Note:  Method 8260B replaces Method 8240.
