摘要：

Computer methods make possible the detailed analysis of chromatographic peak shape, and can be used to obtain the various moments of experimental peaks. The importance of the statistical moments and related properties is discussed here. The moments characterize a peak completely and are related to parameters such as theoretical plate height and forms of asymmetry such as peak tailing. They may also reflect peak contamination. A rapid and accurate method for measuring moments is described. This involves a digitizer coupled with a gas chromatograph. The data obtained are analyzed by a Univac 1108 computer. © 1969, American Chemical Society. All rights reserved.
