Abstract: In this work, the "retention time gradient effect" of gradient GCcolumns is intensively studied to establish some equations and formulas for structure calculation of chromatographic columns. In addition, the relevant computer programs are designed.

Key words: GC column, Gradientally loaded GC column, Retention time, Gradient effect
