Isogeochem: I am requesting any suggestions regarding use of molecular
sieve to absorb N2 for natural abundance measurements.
Can someone share their expertise on which mole sieve to use or any advice?
Thank you and best wishes, jeff o.

To collect Nitrogen we use Porapack Q. It is kept in the tube by a glass filter (sort of frit). You have to warm the porapack well to get all nitrogen off. It works like isolation material, the inner stays cold and holds some nitrogen. Like in the former message you have to degas the porapack very well before use .
