Abstract: | Summary Fused silica is by far the best material for most kinds of GC capillary columns but in some particular conditions, when a
drastic 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 quartz-lined 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. |
