Thermal Diffusion Factor of Neon from Column Measurements

Thermal diffusion factor of neon at 300.5 °K has been determined to be 0.0205 ± 0.002, by means of separation studies, with and without the introduction of spacers, in a hot-wire thermal diffusion column of 1.42 m length. The theory propounded earlier by the authors for evaluation of parasitic remixing is used. Within the experimental error the above value agrees fairly well with the calculated value on the basis of exp −6 potential model.
