Abstract
This investigation was undertaken to study the separation characteristics of helium, hydrogen, and deuterium on a specially prepared capillary column. Complete separation of helium, parahydrogen, orthohydrogen, paradeuterium, and orthodeuterium was achieved by using neon as a carrier gas with an 82-m by 0.28-m, id, soft-glass capillary column with an etched internal surface. The operating temperature range of 29 deg. to 60 deg. K was obtained by using a helium refrigerator. The interaction of helium with the column's adsorptive surface was found to be small at these temperatures.
