我国气相色谱仪品种虽不少,但是适用于硅烷气中微量杂质分析的产品却为数不多,我们采用四川仪表九厂(亦称四川分析仪器厂)生产的SC—8型气相色谱仪解决硅烷气中的微量杂质分析,效果较佳,操作方法稍加改进不必更换入气口、出气口的管道,即可连续操作获得所需要的五种杂质含量分析数据。如再 Although many varieties of gas chromatography in China, but for trace impurities in silane gas products are few, we use the Sichuan Instrument Nine Factory (also known as Sichuan Analytical Instrument Factory) production of SC-8-type gas chromatograph to solve the silane Trace impurities in the gas, the effect is better, the operation method is slightly improved Do not have to change the inlet, outlet pipe, continuous operation to obtain the required five kinds of impurity content analysis data.
