摘要
本文介绍根据光电离原理、设计了一种便于携带、快速响应的仪器,可以用于现场检测有害气或蒸汽,尤其适合于有机蒸汽和气体的检测。仪器中采用的光电离源是一光子能量为10.2电子伏特的真空紫外辐射源,气体进样泵速为0.5升/分.仪器的检测范围为1～1000ppM,响应时间小于30秒。
Based on the principles of photo-ionization, a portable rapid response analyzer is designed which can be used te detect hazardous gases and vapours on site. It is particularly suitable for detecting organic vapours. A Vacuum ultraviolet radiatien source with photon energy of 10.2 eV is used. The speed of the gas sampling pump is 0.51 L/min. The measurement range of the analyzer is 1-1000 ppm and response time is less than 30 sec.
