[LDCCL]

Thanks in advance

I use 2 helium DIDs and have done lots of O2 analysis (as an impurity), but I don't understand what you're asking. Could you eloborate and give a bit more background?

i have DID with congruation of MS column and DE-OX columns, as you know the DE-OX need to regenerate when running sample over 100 times, so i just want to the DE-OX the columns special property and how to seperate impurities in pure Oxygen

Many thinks in advance

I understand what you're doing, but I have never analyzed pure O2. I'm afraid I can't be very helpful.
