三氯乙烯Cl2C=CHCl气体测毒管134SB TRICHLOROETHYLENE 0.2-36.8

简要描述:

三氯乙烯Cl2C=CHCl气体测毒管134SB TRICHLOROETHYLENE 0.2-36.8ppm,检知管法(detectortubemethod)指用试剂浸泡过的载体颗粒装在玻璃管中,当被测空气以一定速度抽过此管时,被测物质与试剂发策颜色反应,然后根据颜色的深浅和色柱的长短,与标准色板或浓度标尺进行比较,从而作出定性和半定量的分析方法。所用载体应具亩下列性能:(1)化学惰性,即不与被测物质和试剂起反应;(2)质地牢固,并能粉碎成一定大小的颗粒;(3)白色多孔或表面粗糙的固体物质。
