美國SKC硅膠采樣管
美國SKC采樣管Silica Gel采用硅膠采樣極性烴吸附材料，低分子量的硫醇、甲醇、胺、無機酸。處理的硅膠管也可使用，如2，4-二硝基苯肼醛采樣，硫酸處理氨。
Silica gel is the adsorbent material for sampling polar hydrocarbons, low molecular weight mercaptans, methanol, amines, and inorganic acids. Treated Silica gel tubes are also used, e.g. 2, 4-dinitrophenylhydrazine for aldehyde sampling, sulphuric acid treated for ammonia.
