Gas chromatography (GC) systems detect a wide range of gas species. Yet, current GC systems are limited by short channel lengths that inhibit successful sample separation.

University of Utah researchers have developed a gas chromatography system that increases channel length without any increase in overall system size. In effect, less pressure is required to run samples through the longer channels, enabling micro-scale separation. The system’s small size reduces overall energy consumption, package size, and dead volume while increasing separation capacity.
