PRINCIPLE | |
| |
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. | |
APPLICATION | |
| Mode 1: Sampling before decompression 1. No damage to microorganisms by drop in pressure 2. Automatic sampling 3. Automatic decompression release |
Mode 2: Sampling after decompression 1. High compatibility 2. Automatic sampling 3. Accurate sampling | |
