Silica Gel Sorbent Tubes

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.
