金属填充GC色谱柱（常规配置）

In a packed column, 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 R is a styrene-divinylbenzene copolymer with -O- and -N- groups and maximum operating temperatures of about 250 °C.

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。
