Two-dimensional liquid chromatography (2DLC) is a powerful separation technique that employs a second column to further separate fractions taken from the first column; when utilized in an on-line fashion, 2DLC can result in much higher total peak capacities than are achievable with a single column. This computational work addresses the significant challenge of selecting an optimal column pair from the N2 possible combinations (order matters in the on-line approach) by presenting a predictive screening method for column pair selection, and provides insight into the defining characteristics of a good column pair.
