801 is designed for sampling organic solvents in environmental air, particularly for polar solvents such as Methanol and Acetone which cannot be sufficiently adsorbed onto charcoal.
Organic solvent vapour is adsorbed onto the silica gel while passing through the tube. Adsorbed solvent is recovered with a desorption solvent followed by gaschromatographic analysis. When sample air corresponding to 60 to 80 & of the amount causing breakthrough is passed, the colour begins to change from blue to pink by the moisture from the silica gel side predicting breakthrough.

801是专为抽样,尤其是如甲醇,丙酮极性不能得到充分的炭吸附溶剂到环境空气中有机溶剂。

有机溶剂蒸气吸附到硅胶管,同时通过传递。吸附溶剂回收与gaschromatographic分析奉行脱附溶剂。当空气样本对应60至80及造成的数额突破是通过颜色开始由蓝粉的水分从硅凝胶方变化预测的突破。
