µPAC™ LC, a new era in column-to-column reproducibility
The main goal of this study is to compare the column-to-column reproducibility of the μPAC™ capLC column format to state-of-the art commercially available packed bed column alternatives. The basic performance characteristics of the μPAC™ capLC have already been discussed in previous technical and application notes*. Reversed phase capillary LC analysis of a protein tryptic digest (Cytochrome C digest) is performed on a series of columns (three column types, n=3), and column-to-column reproducibility is compared in terms of retention, efficiency and peak shape.
