一、前言遵照毛主席关于“我们的责任,是向人民负责”及“预防为主”的教导,和科学研究必须为工农兵服务的方针。我们和上海石油化工总厂卫生防疫站一起,用QSP-1型气敏半导体检定器气相色谱仪,对上海石油化工一厂乙烯装置区的大气,采用注射器直接取样进行了分析。对大气污染物中微量或痕量有机与无机气体的分析。一般需用冷冻(或吸附)浓缩法采样,操作麻烦费时,而气敏色谱仪,具有设备简单。灵敏度高,和载气可用空气等优点。可直接
I. Foreword In line with Chairman Mao’s guideline on “Our responsibility is to be accountable to the people” and “prevention first”, and the scientific research must serve the workers, peasants and soldiers. We and the Shanghai Petrochemical Plant Health and Epidemic Prevention Station together, with QSP-1-type gas sensor gas analyzer, ethylene plant in Shanghai Petrochemical First Factory area of the atmosphere, direct injection syringe was analyzed. Analysis of trace or trace organic and inorganic gases in air pollutants. Generally need to freeze (or adsorption) concentration method of sampling, the operation cumbersome and time-consuming, and gas chromatograph, with a simple device. High sensitivity, and carrier gas available air and so on. Can be direct
