OSTI ID:6599872
The report gives results of a literature review and laboratory research associated with applying the volatile organic sampling train (VOST) to the sampling and analysis of water-soluble, volatile, principal organic hazardous constituents (POHCs) and products of incomplete combustion (PICs). The collection efficiency of each component of the VOST was established for each compound. The accuracy of current analytical methods for analysis of volatile POHCs and PICs when applied to volatile, water-soluble POHCs and PICs was determined. New analytical techniques were developed and evaluated against existing methods. Modifications to the existing method of analysis (EPA Method 624) which were evaluated include elevating the purge temperature from the standard (20/sup 0/C) to 60/sup 0/C, adding g of either sodium chloride or sodium sulfate salt to the sample before purging, and a combination of both modifications. These modifications improved purge efficiency by about 100% or more for the compounds analyzed.
