If compressed air from an inexpensive compressor is used as a supporting gas for flame ionization detectors (FID) used in gas chromatographs, it not only increases background levels, but also causes baseline fluctuations that are synchronous with the compressor switching ON or OFF. Even though Shimadzu GC detectors offer high sensitivity, using this type of compressed air makes it difficult to achieve high-sensitivity analysis using a capillary column. However, an AGE-1000 air gas purifier can be used to remove hydrocarbons from compressor air in order to generate compressed air with hydrocarbon levels lower than Grade 1 high-purity gas (hydrocarbon concentration of 100 ppb). By reducing the hydrocarbon levels in compressed air, the AGE-1000 enables high-sensitivity GC-FID analysis equivalent to using expensive compressed air cylinders.

Note: Install a sealing plug at the FID column connection.
Note: The compressor startup interval is shortened.
