一般描述

GC columns are of two types; packed column and capillary column. Capillary column carries the gas through a central aperture which is unimpeded through the entire length of column. In general, capillary columns are made longer to produce more theoretical plates. This also helps in band dispersion eventually narrowing the peaks and resulting in high resolution. Metal capillary columns should be cleaned to remove traces of extrusion lubricants before being coated.
For less demanding applications where the inertness of glass is not required, choose more economical stainless steel. Column can be carefully bent to fit most instruments.

应用

Empty column may be used for packing adsorbents.
