Online Gas Chromatograph

Online gas chromatographs use a carrier gas to transport samples into the chromatographic column, leveraging the differential adsorption capacities of stationary phases to separate components, while detectors convert concentrations into electrical signals. They are used for real-time monitoring of volatile organic compounds in industrial processes, enabling continuous analysis of gases or volatile liquids in the chemical and environmental protection sectors.
Selection
When selecting an online gas chromatograph, it is necessary to consider the boiling point and polarity of the measured substances to match the type of chromatographic column. Choose detectors such as FID or TCD based on the detection limit requirements. Confirm that the explosion-proof rating is suitable for the on-site environment. The sampling system must be compatible with the pressure of the process pipeline, and the data interface should match the control system.
