Description

General description

The carrier gas percolates through the porous bed in a packed column. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow rates to tolerate the elevated pressures. Porapak N is composed of porous polymer beads which provides significantly lower background at the carbon emission line. They are suitable for separation of H₂, CH₄, CO₂.

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

Stainless steel coulmns with Porapak N and molecular sieve may be used to determine the methanogenic degradation by analyzing headspace gas with GC.
