Mass transfer kinetics, band broadening and column efficiency.
Fabrice Gritti,Georges Guiochon +1 more
TL;DR: This work underlines the areas in which improvements are needed, an understanding of the contribution of the external film mass transfer term, a better design of HPLC instruments providing a decrease of the extra-column band broadening contributions to the apparent HETP, and the development of better packing procedures giving more radially homogeneous column beds.
