NO-NO2 analysis in pure N2O

[tiger1076]

Hello,
I have to do the analysis of 10ppm NO-NO2 in pure N2O. Do you have some suggestions regarding the columns selection. (NO-NO2 can be in one peak or separate)
I have in mind using the PDD in Helium to do the application.

Thanks for your help

Why would you want to use anything but Porapak P or Q to do this?

Both separate NO and NO2 from N20 and both put the two peaks ahead of N2O.

What happened to your reference from Water or Varian for the RRTs of gases on Porous Polymers?

backflush to vent or Heartcut-BF to vent, both are two columns.

I would use a P followed by a Q.

You never wrote me with the info you were going to send. chromatographer1 at the ya hoo place or A O L place.

best wishes,

Rod
