Through retrieval in G1033 As, D.01.00 NIST'02 standard mass spectrum database, the nomenclature, chemical formula,
molecular weight and retention time of corresponding components to the characteristic peak have been recorded. 11
characteristic peak have been found in the total ion chromatogram of Sample 2(smoke produced by combustion of gasoline
on the carpet), and 9 characteristic peaks for Sample 3 (smoke produced by combustion of diesel on the carpet), 8
characteristic peaks for Sample 4 (smoke produced by combustion of lacquer thinner on the carpet), 9 characteristic peaks
for Sample 5 (smoke produced by combustion of alkyd diluent on the carpet).
