ASTM D6420-99(2010)

1.1 This test method employs a direct interface gas chromatograph/mass spectrometer (GCMS) to identify and quantify the 36 volatile organic compounds (or sub-set of these compounds) listed as follows. The individual Chemical Abstract Service (CAS) numbers are listed after each compound.

This field test method determines the mass concentration of VOHAPs (or any subset) listed in Section 1.

Multiplying the mass concentration by the effluent volumetric flow rate (see 2.2) yields mass emission rates.

This field test method employs the typical laboratory GCMS techniques and QA/QC procedures.

This field test method provides data with accuracy and precision similar to most laboratory GCMS instrumentation.
