Field of application
The OUSAF46 UV sensor monitors the concentration of your product at two discrete wavelengths. It covers a broad concentration range and supports you e.g. in optimizing chromatography control. Its outstanding filter performance ensures highest linearity and full consistency with lab results. This provides you with fast and reliable process information and increases your product yield. You also benefit from Easycal – the patented system for easy, liquid-free online calibration traceable to NIST.
The OUSAF46 sensor measures the UV absorption at two specific wavelengths for:
Measurement of protein concentrations
Chromatography control
Permeate and retentate monitoring
Concentration measurement of organic compounds
Aromatics detection
Filter monitoring
Benefits
Covers a wide measuring range thanks to the second UV wavelength
Fast and reliable monitoring of product concentration for better process control and simplified quality control
Precise measured values with full consistency to laboratory results
Patented EasycalTM system option for easy, liquid-free online calibration traceable to NIST
Outstanding filter performance provides highest linearity
Suitable for cleaning-in-place (CIP) and sterilization-in-place (SIP)
