| Abstract: | Objective]To establish a method for determining 13 poisonous organic compounds in the workplace air by GDX102/activated carbon mixed sample tube-thermal desorption gas chromatography. Methods]The appropriate proportion of the solid adsorbents and filling process were selected,and the parameters of thermal desorption gas chromatography was optimized. Results]After the analysis by thermal desorption gas chromatography,the recovery rate reached at least 95%,detection limits were 0.006~0.2 mg/m~3,and RSD ran... |
