ChromGas ZAG generators provide a continuous stream of hydrocarbon free air from an external dry compressed air source, off ering superior limits of detection over and above other modes of supply. Flow rates range from 3.5 L/min to 30 L/min and can support up to 75 fl ame detectors.

• UHP organic free air for GC

  Increase resolution and detection limits of analysis

  Compact design

  Minimal operator attention required

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.
