| Abstract: | Against the disadvantages of those existing methods for indoor air volatile organic compounds(VOCs) determination,preconcentration combined gas chromatography-mass spectrometry has been evaluated for thirty-nine kinds of volatile organic compounds(VOCs) in indoor air.This method is sensitive,simple,precise,and its repeatibility is much better.Thus,it is suitable for determination of VOCs in analyzing the indoor air. |
