Abstract: The invention provides a method for controlling contaminants in biopharmaceutical purification processes by using light scattering and UV absorbance to establish a determinant. The invention makes use of multi-angle light scattering (MALS) and UV as a continuous monitoring system to provide information about the elution peak fractions in real-time instead of conventional pooling methods that rely on a predetermined percent UV peak max value to initiate the pooling process; regardless of product quality.

Abstract: Systems and methods used to control tangential flow filtration are provided, including control systems and methods for use with connected systems with upstream processing units, such as chromatography processing units, in fluid communication with a tangential flow filtration processing unit. Also included are control systems and methods for performing continuous concentration using single-pass tangential flow filtration with permeate flow control.
