Comparison Analysis of On line VOCs Monitoring System and SUMMA Canister Sampling GC MS |
| |
| Abstract: | The volatile organic compounds (VOCs) in standard gas and actual air samples were analyzed by using on line VOCs monitoring system and SUMMA canister sampling GC MS. The two methods were compared. The causes of deviation were analyzed. Suggestions on operation and maintenance of on line VOCs monitoring system also were proposed. The results showed that on line VOCs monitoring system and the laboratory analysis method were comparable. On line VOCs monitoring system could be applied in determining VOCs in the atmosphere. |
