Abstract

A new type of packed glass capillary column (PGCC) with a core, and its potential usage in practice are described. The permeability of the column is considerably greater than that of conventional PGCC and its N/(P~i~‐P~o~) value is also higher. This novel PGCC column has been successfully applied to the analysis of trace levels of ethyne, cyclopropane, propadiene, propyne, and other C~1~ο£ΏC~4~ impurities in pure ethene, propene, 1,3‐butadiene, and catalytic cracking gas samples as well as other petrochemical gases such as liquified petroleum gas.
