Abstract
The baseline drift occurring during a temperature or flow rate program in a chromatographic separating column is compensated for by signals from a function generator. The function generator supplies a computed baseline signal which is a representation of the baseline drift as an analytic function of the temperature, computed with specific separating column parameters. The parameters are determined in a prior test run and inputted into the function generator.
