ABSTRACT:
A process for extracting and analyzing virtually any sample which may be contaminated with pollutants, toxics or other impurities. The process can be used to extract and analyze one contaminant, such as a volatile compound (gasoline), or the process can be used to extract and analyze several contaminants, including both volatiles and semi-volatiles. The process comprises a vacuum extraction technique followed by a heating/cooling cycle comprising a series of heating and cooling stages.
