In a distillation column, which for control purposes cannot tolerate the inherent dead time between analysis of consecutive samples in chromatograph analyzers, the chromatograph output is frequently corrected by inferring a dynamic correction based on the temperature change of a selected tray in the column. The dynamic correction applied to the distillation analyzer essentially eliminates the inherent dead time for obtaining a chromatograph analysis, and accordingly increased the rapidity of response of the column controls which rely on chromatograph analysis.
