Analysis of products of the industrial synthesis of ethylene oxide by two-dimensional gas chromatography using packed capillary columns

Procedures for separating products of the synthesis of ethylene oxide by two-column gas chromatography using both conventional capillary PLOT columns and packed capillary columns of a new type bearing microparticulated adsorbents are proposed. A combination of packed capillary columns with a microthermostat reduces both separation time and the size of the chromatographic system, which becomes compatible with microreactors. The short time of analysis enables the control over the work of a series of microreactors in a cyclic mode using one chromatographic system.
