Hi Lampros!

Perhaps a naive question, but I will ask it anyway. Did you try molecular sieves?

Hi Lampro,

Obivious you not usung nitrogen from cylinder, because gases from cylinders usually have very low humidity. Myabe your nitrogen gas source, is a nitrogen generator. So, if I assumed right, my suggestion is to order from Sigma Aldrich a tube with proper catalyst and with diamentions that are suitable for you (type of connections, flow values and percentage of humidity you want to vanish). There is a whole section at Aldrich cataloge that you can choose.

I wish to help you

Thank you all for your contributions I believe I received the information I was seeking.
