Summary
Eluate transfer between coupled columns by flow switching, backflushing of the pre-column, and other procedures of multidimensional chromatography (MDC) are invaluable techniques to save analysis time to improve resolution, to gain more and better chromatographic information and to prevent contamination of main (high resolution) column and detectors such as ECD and TID. It is of advantage to maintain the coupled columns at different temperatures. Double oven instruments should therefore be used with advantage in multidimensional gas chromatography (MDGC). Flow switching can be done in between and after the system of coupled columns. Also, reactors can be coupled to high resolution columns with advantage [5].
