| Abstract: | With SUMMA canister sampling-air preconcentrator,gas phase cold oven and Deans Switch cutting technique,C 2 and C 3 components were trapped into HP-PLOT/Q+PT column and determined by FID detector.Other components were separated by DB-1 column and determined by mass detector(MS).It was realized for simultaneous determining 57 kind of PAMS compounds and 65 kind of TO-15 compounds in ambient air with just one injection.The results showed that 108 kinds of VOCs had good linearity in the range of 0.15 nmol/mol to 8.0 nmol/mol,the detection limits were from 0.04μg/m^3 to 2.8μg/m^3,the RSD of relative response factor was not more than 30%. |
