Hydrogen and Deuterium separation

[Jolanda]

Hi All,
I have an Agilent7890 and there is a channel for the determination of hydrogen, but it is absolutely unsuitable for separation hydrogen and deuterium. Could you please advise what the columns, molecular sieves are better to use for this purpose?

If I remember correctly, a packed column of specially prepared molecular sieve will perform this separation. I believe Supelco technical service may have that information.

This was done over 30 years ago, please excuse my poor memory of the details.

Review: United States Patent 4276060

Best wishes,

They used a TCD but if you needed really low levels this is the ideal application for an HID (standard disclaimers apply here.)

Hi
this separation can be done easily on a Molsieve 5 A capillary columns. Need long columns (50 x 0.32mm) and low temperature (- 78C);

If you go down to -150C you can also separate the hydrogen - spin isomers
