haohan大气中总烃测定直接进样法填充柱1.5m*1/8，60-80目

浩瀚色谱（山东）应用技术开发有限公司用活性炭低温(液氮为冷源)吸附法净化氢气以代替高纯氢发生器,用催化净化法净化载气和助燃气,从而提高了GC-790气相色谱仪的灵敏度。本方法ZUI低检出限0.02ppm,相对偏差1.5％,变动系数4.9％,分析周期10秒。文中还此较了三种催化剂的净化效果和七种材质采样器的样品保存时间。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses activated carbon low-temperature (liquid nitrogen as a cold source) adsorption method to purify hydrogen instead of a high-purity hydrogen generator, and uses catalytic purification method to purify carrier gas and auxiliary gas, thereby improving the sensitivity of the GC-790 gas chromatograph. This method has a low detection limit of 0.02 ppm, a relative deviation of 1.5%, a variation coefficient of 4.9%, and an analysis period of 10 seconds. The purification effects of three catalysts and the sample storage time of seven material samplers were also compared.
