GC-PID测定大气中痕量烃类化合物及可靠性

Determination of Trace Hydrocarbon Gases by GC-PID and Its Reliability Analysis

把气相色谱仪 (GC)与自行研制的光离子化检测器 (PID)联用 ,实现了大气中痕量烃类化合物的直接测定 ,给出了仪器的构成、性能指标。

A method to analyse trace hydrocarbons in the air by GC-PID is introduced. The constructure and working principle are discribed. Both of specification of the instument and the analysis results are given. The reliability of the results is analysed too.
