摘要：

The total number of theoretical plates for two or more chromatographic columns connected in series is often less than the sum of theoretical plate numbers for the individual columns. As a result, it is generally unwise to couple together columns which differ markedly in efficiency (HETP values), column diameter, or composition. Corresponding variations within a single column or bed should also be avoided. These and other aspects of coupled-column operation are examined. © 1968, American Chemical Society.
