摘要

本文根据声SAW探测器在气相色谱/声SAW气体传感器系统中传感位置与冷凝吸附效应的关系，对气相色谱/声SAW气体传感器系统的响应进行了研究，并分析了声SAW探测器在气相色谱柱出口位置对气相色谱/声SAW气体传感器系统响应的影响。采用不同位置排列的声呐装置在气相色谱/声呐中检测甲基膦酸二甲酯(DMMP)。当气相色谱柱出口对准SAW检测器的中间位置时，传感器性能优越，响应差约为30%，不容忽视。

Study on the sensing position of the saw detector in GC/SAW gas sensor system

This paper reports some work on SAW gas sensors based on the condensation-adsorption effect relating to the sensing position of the SAW detector in GC/SAW gas sensor system, and analyzes the response of GC / SAW gas sensor system influenced by the position of the SAW detector where the GC column outlet is aligned at. The SAW device aligned at different position is used in GC/SAW for the detection of dimethyl methylphosphonate (DMMP). The sensor has a superior performance when the GC column outlet is aligned at the middle position of the SAW detector, and difference of response is of ~30%, which could not be ignored.
