Prediction of Elution Profiles in Countercurrent Chromatography With a Linear Loss of Stationary Phase

Journal of Separation Science, Volume 49, Issue 9, September 2026.
A common challenge in reliably predicting elution profiles in countercurrent chromatography using the ProMISE2 software is a persistent loss of stationary phase (i.e., bleeding). This drawback can be overcome by a simple calibration method in the case of linear bleeding.
