ADVANCES IN PREPARATIVE GAS-CHROMATOGRAPHY FOR HYDROGEN ISOTOPE-SEPARATION

Early and recent developments of preparative gas chromatography for hydrogen isotope separation are briefly reviewed. Advanced gas chromatography techniques including peak cutting and temperature programming are discussed in detail. A novel position temperature programming technique which allows the column to be overloaded so that a surprisingly large amount of mixture can be processed in a relatively small column is introduced. This technique may have wide applications in gas chromatography other than hydrogen isotope separation.
