| Abstract: | Microtrap technique can connect the sample and GCMS,which accomplished on-line sampling-pretreatment-analysis.The trace VOCs,MT-GCMS method shortened the pretreatment time,and reduced the operation expenses and the analytical expenses.Therefore,it was a small,simple,effective adsorption and desorption technique which eliminated the need for solvent and complicated apparatus,despite of its low price.The analysis of trace VOCs in ambient air can be automatic by MT-GCMS. |
