摘要：

For temperature-programmed gas chromatography, it is shown that the first original, the second and the third central moments of a moving zone are additive along all parts of the component passing through in a linear system. Trace expressions for zones moving along the column and expressions for the calculation of the first three moments (retention time, peak variance and third central moment related to peak skew) of peaks according to isothermal data are derived. It is also shown that the definition of local plate height and related equations for peak variance in the literature are not correct. Reasonable definitions of local plate height and related equations are then developed appropriately. © 1990.
