The difference between high purity nitrogen and nitrogen

Release time:2023-03-29

Chromatograph carrier gas

purity ≥99.999% of high pure nitrogen (import price is very high), domestic and foreign counterparts currently generally use PSA nitrogen technology can only produce nitrogen purity of 99.9% of general nitrogen (O2≤ 0.1%), individual enterprises can produce 99.99% of pure nitrogen (O2≤0.01%), Higher purity from PSA nitrogen production technology is possible, but the production cost is too high, the user is difficult to accept, so the use of non-low temperature nitrogen production technology to produce high purity nitrogen must also add a post-purification device.
