摘要：
The effectiveness of vapor detectors can be enhanced by the addition of a preconcentrator which collects explosives molecules and releases tis concentrated sample to the detector for analysis. Candidate preconcentrator materials for detector applications were evaluated using a gas chromatograph and a commercial explosives vapor detector. The saturation time and release temperature for nine materials were obtained using ethylene glycol dinitrate and 2,4-dinitrotoluene explosives. Based on these data, the best candidate for use in a thin-screen preconcentrator for the above explosives in OV-275. © 1979.
