WebDiafiltration can be performed in either continuous or discontinuous mode. Discontinuous diafiltration refers to a practice where the sample is first concentrated, then diluted with exchange buffer to the initial starting volume, followed by another concentration step. This process is repeated until the desired microsolute has been exchanged. WebDiafiltration is an indispensable tool in separating multicomponent process streams and widely used in the food and beverage, chemical, biotechnological, and pharmaceutical industries. This article introduces the reader to the fundamentals of diafiltration. It provides a brief survey on the most important applications and discusses the various ...
