Abstract
THE chromatographic separation of argon and oxygen is difficult, and existing methods depend on one of the following techniques:
(1) Separation on a molecular sieve 5 Å column at 18° C (ref. 1) and at −80° C (refs. 2–4).
(2) Chromatographing argon and oxygen as a composite peak on molecular sieve 5 Å at 100° C; removal of the oxygen with a reducing agent allows the argon peak only to be developed5–7.
(3) Separation of argon and oxygen on a column of firebrick loaded with 8 per cent by weight of blood at 20° C (refs. 8 and 9).
