Determination of 45Ozone Precursors Compounds(PAMS)in Ambient Air by Domestic Portable gas Chromatography-Mass Spectrometer
Adetection method for the determination of 45 PAMS in ambient air was established by using domestic portable GC-MS.The45compounds were separated and determined well,and had a good linear relationship in the range of 2 nmol/mol～50 nmol/mol,the correlation coefficients were all more than 0.990,the detection limit of each component was 0.20 to 1.23 nmol/mol,and the relative standard deviation(RSD)were1.02%～14.05%(n=6),a recovery range of 73.0%～106%was obtained in ambient air samples.Through determinationand comparison of the actual sample,the results shows that this method has the advantages of short detection time,high sensitivity,good precision and accuracy,simplicity,which is applicable to the on-site analysis of the 45 PAMS in ambient air.
