How do you take samples of gas in a negative pressure pipeline? Is there any available negative-pressure sampling equipment? I would appreciate your advice?
Well, there are many negative pressure samplers available; they can be found at many electronic or instrumentation companies as well as distributors
Most negative-pressure pipelines can be sampled using an oil-free vacuum pump; for samples that have already been lost, such as those used for measuring low sulfur compounds, it is best to use a specialized sampler.
Could the two people upstairs provide some detailed information about the manufacturers? I can’t find it online.
Search online for small oil-free vacuum pumps; there are many available.
