The preparation of porous layer open tubular columns using powdered glass as a binding agent

Abstract

The use of finely powdered glass as a binder when mixed with a diatomaceous earth support is described for the preparation of porous layer open tubular (PLOT) capillary columns. The method, which is based on the technique developed by G rant for making PLOT columns using lithium chloride as a binder, produces columns with similar performance characteristics, but which show considerably less residualy activity in the support material than those prepared using the inorganic salt.
