Diafiltration factor
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. WebJan 1, 2016 · Diafiltration Factor.
