摘要：

The design, operation, and initial performance of an automated air sampling and analysis system for the monitoring of volatile organic compounds in air are described. This system, based on miniature solid adsorbent sampling tubes (minitubes) and thermal desorption gas chromatographic analysis, performs capillary column separations without cryogenic refocusing techniques. Capillary column separations equivalent to traditional syringe injection are achieved with a precision of 1 and 5% with respect to retention time and peak area. The system has been field tested and successfully used for the analysis of minitubes containing the chemical warfare agent mustard.
