Despite the theoretical promise of reduced plate heights (h) < 1, most modern UHPLC columns can only deliver plate heights in the range from 1.4 to 2.5. However, improved packing procedures, a better understanding of the colloidal properties of particle suspensions, and the study of the rheological behavior of packed beds and the final bed structure should lead us to practical solutions that can double the column efficiencies.

Is that peak “pure”? How do I know if there might be something hiding under there? In part I of this series, we explore some of the concepts behind peak purity assessments, describe some tools that are used in commercially available software for these assessments,

Here, a procedure is described for preparing polydisperse polymer standards to validate the accuracy of any SEC method for aqueous or organic mobile phases. This approach can be used for all calibration procedures with the exception of online light scattering and viscometric detection.
