Packed column made up of stainless steel are basically employed when higher carrier gas flow rates are employed as they can sustain elevated pressure. Stainless steel columns are usually washed with dilute hydrochloric acid, then with water followed by methanol, acetone, methylene dichloride and n-hexane in order to remove any corrosion products and traces of lubricating agents.
Application: Carboxen 1000 packed in a stainless steel column maybe used in the anaerobic chamber for conductance of research with methanogenic archaea.
