A gas chromatographic method for separating hydrogen isotopes

摘要

The six isotopic species of hydrogen, H₂, D₂, T₂, HT, HD and DT, are separated from isotopic mixtures thereof with improved efficiency by low temperature gas column chromatography using a molecular sieve as the packing material, initially at a temperature of from -185°C to -160°C, but gradually increasing the column temperature at a rate of up to 10° per hour.
