Title: Determination of Benzene,Toluene and Xylene in Building Materials Market Air by Gas Chromatography
Abstract: Benzene,toluene and xylene in building materials market air were determined by using activated charcoal adsoption-CS2 analysis capillary vessel gas chromatography. Activated carbon tube was used to collect samples with FID detector. Linearity of benzene,toluene and xylene were studied,results showed that after process experiment,samples desorption rate was above 90%,Canadian sign returns ratio of benzene,toluene and xylene was 96.6%~102.1%,relative coefficient of linear equation above 0.999. The sampling devices were small size,low noise and easy to operate,which are applicable for fast determining benzene, toluene and xylene simultaneously.
