摘要
介绍了一种新的环境污染痕量气体探测方法——激光质谱法,并给出了定标方法.采用甲苯作为定标的标准样品,用这种方法定量检测了汽车尾气的多种有机污染物.理论研究和实验结果表明,激光质谱法是一种有效的痕量污染气体的多组分在线检测方法.
In this paper a new method for detection of pollution trace gases with laser mass spectrometry is presented and the calibration procedure is also given. With toluene as calibration gas, organic pollutants from automobile's exhaust gas are determined by the method. It is theoretically and experimentally demonstrated that laser mass spectrometry is an effective tool for trace gases analysis.
