| Abstract: | We have previously described 1] the design of a simple heart-cuttings device based on the Deans' principle of remote pressure switching 2]. Since that time, further work has been conducted to refine the design of the heart-cutting device and to develop complementary backflushing and cryofocusing units. This paper describes the results obtained from an intensive evaluation of the three modules in various combinations and considers parameters critical to the practical application of multidimensional gas chromatography (MDGC). |
