When directly integrated into one or more locations of a process stream, the FlowVPE System reveals process characteristics that, until now, have been hidden due to the limitations of the most commonly-used, on-line, fixed-pathlength UV-Vis solutions.
Capable of making spectral and fixed-point measurements at wavelengths between 190 nm and 1100 nm, at pathlengths between 5 microns and 8 millimeters, the FlowVPE System is adaptable to a wide range of sample types and concentrations. It can support lab scale flow lines of 3 mm, pilot scale flow lines of 10 mm, and manufacturing scale of 22 mm.
The flexibility and robustness of the technology is unparalleled when compared to traditional UV-Vis techniques and equipment.

Protein A280
The FlowVPE System’s in-line variable pathlength system can provide accurate measurement during the downstream process from 0.1 mg/mL to more than 250 mg/mL for an antibody of EC 1.5. No need to remove samples for testing or disrupt production flow.
Drug Antibody Ratio (DAR)
The FlowVPE System can be used to measure the DAR value of antibody drug conjugates (ADC) inline. The software allows the system to measure the ratio between the payload and the protein in real time.
