The concept of theoretical plates is the key measure of column efficiency in chromatography, linking Nobel Prize–winning theory with practical tools for achieving sharper peaks, better resolution, and ...

Waters released the BioResolve™ Protein A Affinity Columns with MaxPeak™ Premier Technology, designed to improve sensitivity and speed in antibody titer measurements. Featuring non-porous 3.5 μm ...

To purify increasing amounts of biotherapeutics more efficiently, the use of high flow rates or greater resin bed heights during downstream chromatography steps is a tantalizing option. A limitation ...

The mobile phase is the starting point for this process. What is the sample polymer soluble in? An insoluble polymer cannot be measured by GPC, making the choice of solvent important. For a fast GPC ...

Users often feel a sense of accomplishment when achieving well-defined, isolated spots with a thin-layer chromatography (TLC) plate. Users set up a flash chromatography method, prepare the column, ...
