Merck, 13052-U, Metal Packed GC Column (General Configuration)

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