一般描述

The carrier gas percolates through the porous bed in packed columns. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of mainly two 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 Q is a porous copolymer of styrene and ethylvinylbenzene crosslinked with divinylbenzene which is applicable for quantitative adsorption.

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。
