Gas Chromatographs (151 suppliers)
Gas Instruments (958 suppliers)
Gas Sensors (576 suppliers)
Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements.

GC Columns (81 suppliers)
Gas chromatography columns (GC columns) are of two types: packed and capillary. Solutes to be measured travel through the column at a rate primarily determined by their physical properties, and the temperature and composition of the column.
