[labnetwork] N2 grade for blow guns

[Leif Johansen]

Hello Iulian, 

Here at DTU Danchip, we are using purified N2 for the guns in fume hoods and wet benches. We have had the same discussion whether it is overkill to do so, since the most of the impurities in our bulk N2 probably stems from water trace. One could argue that the nice clean process N2 becomes dirty the second it leaves the nozzle. However, we have never changed to bulk N2 and most probably will not do so. 

Best regards, 

Leif

Dear Colleagues,

Would it be overkill or a good idea to supply high purity nitrogen (instead of utility nitrogen) to the blow guns located in cleanroom fume hoods?

Thank you for your help.

Iulian
