Parkers ChromGas ZAG generators provide a continuous stream of hydrocarbon free air from an external dry compressed air source, offering superior limits of detection over and above other modes of supply. Flow rates range from 1 L/min to 30 L/min and can support up to 75 flame detectors.
When combined with ChromGas H2F, the system forms a modular FID gas station suitable for all known GC combustion detectors such as FID, FPD, and NPD. Its state-of-the-art control system elevates both user-friendliness and performance monitoring.
