金属填充GC色谱柱（常规配置）

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.† Chromosorb W is a fragile white solid which is prepared by heating diatomaceous earth with a flux. The resulting fine structure is cemented over glass which results in large and irregular pores.† HP is the classification of a support as high performance grade.†

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。
