Summary
Capillary glass columns have been successfully used in laboratory gas chromatography for a long time [1,2]. Because of the high resolution of these columns they are also well suited for process chromatography. Their application, however, was not successful previously because of four main problems:
-
1.
a column switching system with suitable fittings,
-
2.
suitable sampling valve,
-
3.
mechanical instability,
-
4.
short life-time.
The fundamental works of Deans, Kaiser, Schomburg et al. [3–6] solved many of the problems that arise in the use of capillary columns for process chromatography. In the following we analyse these problems in detail.
