Description

The Raman flow cell meets the speed demands of downstream by optimizing Raman collection for low-turbidity, low volume samples. Ideally suited for development-scale flow rates, the Raman flow cell allows real-time monitoring, rapid process optimization, and process control for chromatography and other downstream unit operations.

Field of application
  • Downstream: aggregation, protein crystallization, formula stability, product CQA, protein concentration, buffer excipients
Benefits
  • The Raman flow bench houses a Raman flow cell and easily connects to an Rxn-10 probe paired with a Raman Rxn embedded analyzer, and ensures transferability when used with the Raman flow assembly calibration and verification kit
  • Provides continuous, real-time measurements with high sensitivity for development-scale flow rates  
  • Achieves lower limits of detection through enhancement of the Raman signal  
  • Brings Raman-based process insights and control to downstream bioprocessing unit operations
