Description

Description générale

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. The GC column made up of Carbowax -20M liquid phase on a Carbopack B support packing material is highly efficient, has low bleed and almost no active site. Furthermore, it guarantees uniform packing in the column thereby leading to rapid analysis.

An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.

Application

Carbopack B or graphitized thermal carbon block (GTCB) maybe used for the determination of trace amounts of simazine and atrazine in water. It was also used for the Gas chromatographic evaluation of the organic components present in the atmosphere at trace levels for pre-concentration of the sample.

Autres remarques

This is a micropacked column. It is packed full and contains stainless steel screens.

This column is preconditioned.
