Abstract
The gas chromatographic separation of the components of a complex mixture of industrial solvents, not possible on a single stationary phase owing to coelution of some of the compounds, has been achieved on two serially connected wide bore capillary columns of different polarity.
The analysis of a mixture of twenty five compounds was optimized using the serial gas chromatography theory of Purnell and Williams. The capacity factors of sample components measured with the two columns coupled in series were found to agree with those predicted by theory, regardless of the order in which they were connected.

## Abstract Preliminary results on thickβfilm wideβbore (0.53mm i.d.) columns for GC preparation of pure enantiomers are described. In particular the loading capacity for several racemates of a 3ΞΌm, 30% 2,6βdiβ__O__βmethylβ3β__O__βPentylβΞ²βCD/OV1701 column and of a 2 ΞΌm, 30% 2,3βdiβ__O__βacetylβ6β_
Gas species separation in thin capillaries is proposed based on the non-resonant interaction of polarizable gas molecules with an optical lattice produced by the interaction of two counter-propagating laser beams. Analytical expressions are developed for the evaluation of separation efficiency based
Gas chromatographic equipment and procedures are described for automated splitless injection of pseudo-static headspace samples collected externally onto a sorbent trap. The GC microprocessor controls, in sequence, carrier gas backflushing of the sorbent trap for water removal, splitless thermal des
