INSTRUMENT FEATURES
◎ Zero-level air is a device that purifies air sources by catalytically cracking the total hydrocarbons in compressed air to produce zero-level air with less than 0. 05ppm hydrocarbons. In the heated catalyst with platinum and palladium carriers, hydrocarbons are converted into carbon dioxide and water vapor. The instrument uses British Peculiar silicone rubber rings (low sulfur content) internally, effectively improving gas quality and ensuring stable GC baselines.
◎ The zero-level air generator provides auxiliary gas for GC-FID, FPD, NPD, etc. , and can also be used as spray gas and auxiliary gas in LC/MS, as well as auxiliary gas and carrier gas in total organic carbon analyzers (TOC).
