Dear All,
At the moment i am reading a lot of papers about gas chromatography theory. But I never found anything about the theory of chromatography columns (packed or coated) with round or rectangular cross- sections. Please help me, if you have any information about this!
Thank you very much for your efforts.

Efficiency of a packed column depends mostly on packing material - its size, shape, regularity of packing, etc., - and should not depend on non-exotic (circular, elliptical, rectangular, etc.) shape of a column cross-section.

Golay published several papers by on open tubular columns of different cross-section shapes:

Golay, Marcel J. E.:

1. On circular and rectangular cross-section: Desty, D. H., (Editor), Gas Chromatography 1958. Academic Press, New York, 1958, pp. 36-55.

2. On elliptical cross-section: J. of Chromatography, 196 (1980), pp. 349-354.

3. On rectangular cross-section: J. of Chromatography, 216 (1981), pp. 1-8.
