金属填充GC色谱柱（适用于Agilent，配置“A”）

In packed columns, the carrier gas percolates through the porous bed. 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. Chromosorb W, a fragile white solid prepared heating the 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.

在不需要玻璃惰性的、要求不高的应用中，应使用经济的金属柱。该色谱柱适用于Agilent 5880、5890、6890、7820和7890（配置A，柱上进样，除TCD外的所有检测器）。
