Abstract
Fused silica is by far the best material for most kinds of GC capillary columns but in some particular conditions when a drastic acidic or alkaline treatment is required this material and especially the polyimide protector layer do not possess high chemical resistance and could easily break down In order to overcome this disadvantage in this paper we present a new type of column — a quartzlined aluminum capillary coated with graphitized carbon black modified by liquid phases by using a new coating procedure With the above material a capillary column for amine analysis and another for the analysis of VOCs and oil products are obtained Some characteristic applications of both columns are reported
