Discovering the unknown: How does in silico process development change PD scientists’ work?
A lot of the effects of the thermodynamics that are happening inside the chromatography column are scale independent. Therefore, it's really easy to also predict what happens at a larger or smaller sc…

Report from the 6th International HTPD Conference
Two challenges highlighted were the current practice of using microscale columns since the flow rate is limiting for viral clearance in short columns, and that the precision in the models is not there…

Digitalization: The Route to Biopharma 4.0
In periodic counter-current chromatography, sensor data from ultraviolet absorbance connected at the primary load column can be used to control column loading (21).
Advanced control systems …

Analysis of Glycosylation in Biosimilars
The interaction of the glycans with the column matrix depends on the overall structure of the glycans, not just their mass.
The various antennary structures give different retention times, and thu…
