Adsorption and Chromatography in Bioseparations
This material was developed for a final year undergraduate bioseparations module. There are a number of links to sites for modeling adsorption chromatography. For example, a link to an Excel spreadsheet provides a demonstration of varying N, l, and K (or alpha)affect band separation. Other links explain adsorption isotherms in the context of bioseparations.
