high quality nitrogen generator:
SPN-300/ 500/ GCN-1000 Nitrogen generator use water electrolysis technology, could meet all kinds of gas chromatography requirement.
SPN-300 /500/ GCN-1000 nitrogen generator use pure air as source, use electro-catalysis method to separate air method to produce pure nitrogen. Electricity push layer use PCAN carrier and noble metal as catalyst in order to get pure nitrogen.SPN-300 /500/ GCN-1000 nitrogen generator is controlled by program, output flow rate and output pressure are both very stable.

Machines Characteristics: 
1. Two level nitrogen purifier in order to get ultra pure nitrogen. Also have deoxidizer ( no need to activation ), have special treatment for alkali returning in order to guarantee Safety. Digital display for easy knowing nitrogen flow rate.
2. Machine is controlled by program. Output pressure and flow are
very stable. Flow rate could be adjusted from 0ml/min to maximum flow rate.
3. Advanced technology. Use membrane separation technology. On
the catalyst layer, use PCAN carrier and noble metals, which greatly increased electrolysis efficiency and large  flow rate with pure gas. Before delivery, each electrolysis cell is under at least 100 hours aging testing with large current, which will keep electrolysis cell working stable in future.
4. Three level catalyst, except two level catalyst in the electrolysis cell, also add an extra new noble metal as catalyst, which will guarantee O2 content in the output nitrogen gas  is less than 3ppm.
5. Little moisture in the output nitrogen. Use high efficient membrane to separate mostly Water, also has moisture filter to further remove left water.
6. Easy operation. No need to use heavy nitrogen cylinder, just power on, pure N2 will Be produced. Could use none-stop. Output flow rate will not decrease any longer.
7. Safety and stable: with safety method, to protect alkali returning. Nitrogen generator is an ideal equipment to replace high pressure gas cylinder
