Decompression before sampling
After passing through the sampling/detecting device, the compressed gas flows through the DHPD and
is decompressed into an atmospheric pressure for release.
Decompression after sampling
The compressed gas is decompressed into an atmospheric pressure when flowing through the DHPD, and
then is output to the back-end sampling/detecting device for sampling or detection.
