一般描述

In packed columns the carrier gas percolates through the porous bed and 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 are porous polymer beads which helps in providing significantly lower background at the carbon emission line. They are suitable for separating H₂, CH₄, and CO₂.

对于不需要玻璃惰性的低要求应用，应使用经济型的金属柱。该色谱柱具有一般性配置，并可小心将其弯曲以适用于大多数仪器。

应用

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