Summary
In preparative gas chromatography a column can separate a well defined maximum possible sample size (M. A. S. S.). This depends on preparative scale efficiency (n') of the column, on relative retention values (a) and on partition ratios (k) of the substances. Ways to use these parameters to calculate the M. A. S. S. are described.
Columns can have different shapes and sizes and the characteristics of the extreme possible forms; long–narrow and short–wide, are given. In general a rather long and narrow column permits to solve a large variety of mixtures. Some of the particular problems of preparative gas chromatography are discussed.
