Tailoring orthogonal proteomic routines to understand protein separation during ion exchange chromatography

On-chip technologies for multidimensional separations

We review microfluidic devices designed for multidimensional sample analysis, with a primer on relevant theory, an emphasis on protein analysis, and an eye towards future improvements and challenges to the field. Image shows results of an on-chip IEF-CE separation of a protein mixture; unpublished surface plot data from A. E. Herr.
