| Abstract: | Based on online GC-FID/MS method,the performance indexes of 116 atmospheric VOCs were analyzed including linearity,detection limit,precision,accuracy,period accuracy and period precision.The accuracy of 116 volatile organic compounds measured by GC-FID/MS was systematically analyzed.The measurement accuracy and reliability of 116 VOCs were quantitatively evaluated based on online operation for 7 consecutive days.The results showed that:among 116 species,the linear correlation coefficient(R)of 109 species was≥0.98;the minimum detection limit of the 113 species was<0.15 nmol/mol;the accuracy of the 103 species was within±15%,and the precision of all species was within 15%. |
