Based on the innovative design of the phx42it is now possible to configure the FID phx42 to perform VOC sampling in low oxygen or no oxygen environments such as nitrogen buffers, carbon canisters, VOC tank inspection or other specific applications.
When set to zero oxygen mode, the phx42 ZOM can monitor components that were previously impossible to monitor because there was not enough oxygen available at the probe tip to sustain the hydrogen flame in the FID. This meant that the instrument was subject to persistent shutdowns or unable to operate at all.
This extraordinary functionality is based on the following innovations:
We provide oxygen for the combustion of hydrogen through the scrubber attached directly to the unit.
We made special adjustments to the multiple streams in the detector.
Fine tuning of the hydrogen flow to the flame.
Modified closed loop controls for hydrogen pressure and pump levels to optimize control and accuracy.
