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是專為抽樣，尤其是如甲醇，丙酮極性不能得到充分的炭吸附溶劑到環(huán)境空氣中有機(jī)溶劑。

有機(jī)溶劑蒸氣吸附到硅膠管，同時(shí)通過傳遞。吸附溶劑回收與gaschromatographic分析奉行脫附溶劑。當(dāng)空氣樣本對應(yīng)60至80及造成的數(shù)額突破是通過顏色開始由藍(lán)粉的水分從硅凝膠方變化預(yù)測的突破。
