Chromatographia - Virtual Issue: Macromolecular Separations

In  contradistinction to their small-molecule counterparts, macromolecular separations are generally concerned less with issues of peak capacity and more with the determination of structure-property relations. The polymeric analytes themselves can possess dispersities along more than one physico-chemical dimension having, e.g., broad molar mass distributions as well as broad chemical composition and/or branching distributions. Multi-detector size-based separations, be they column- or channel-based, remain the preferred methods by which to obtain many of these relations. The reviews and original papers presented in this Virtual Issue on Macromolecular Separations highlight some of the diverse work published in CHROMATOGRAPHIA during the last two years in the area of polymer chromatography. We expect contributions to the journal in these areas to continue to grow and welcome your submissions.
