Abstract
A wide-bore capillary column with a methylsilicone stationary phase has been evaluated with regard to its ability to identify substances by means of their retention indices. Column efficiency was compared with a normal packed column and a medium-bore capillary column, and the impact of carrier gas flow and load capacity were investigated. It was shown that under defined conditions retention indices on the wide-bore capillary column were comparable to those available in a data bank obtained on packed columns.
