PostSubject: Pure nitrogen and high purity nitrogen differences between   Fri Jan 14, 2011 4:44 am

The purity of together gas speaking is an important parameter, such as oxygen, nitrogen, Just nitrogen speaking in accordance with purity can be divided into three levels, respectively for industrial use nitrogen, pure nitrogen and high purity nitrogen level 3, their purity respectively 99.5% (O2 acuities 0.5%), 99.99% (O2 acuities 99.999% (0.01%) and more than 0.001% O2).
Pure nitrogen N2 p 99.99 chemical industry, metallurgy, electronic industrial high purity nitrogen N2 p, electronic, mechanical 99.999 scientific research, carrier gas chromatograph industry
So, if that makes no difference for refrigerants, high purity nitrogen mainly suitable for precision instrument
99.999% purity nitrogen purity p outside (import prices high), domestic and international counterparts to current general with PSA nitrogen making technology can only producing nitrogen purity of 99.9% of nitrogen (O2 acuities 0.1%), the individual enterprise can be produced 99.99% pure nitrogen (O2 acuities were 0.01%), higher purity nitrogen making technology from PSA is possible but the production cost is too high, the user is difficult to accept, so use of the cryogenic nitrogen making technology making high purity nitrogen also must add after grade purification devices.
