Optical sensor with the OUA260 flow assembly for the measurement of UV absorption

Application

The sensor measures the spectral absorption of process liquids in the ultraviolet region of the electromagnetic spectrum.

  • Measurement of protein concentrations
  • Chromatography monitoring
  • Filtration monitoring
  • Concentration measurement of organic compounds
  • Detection of aromates
Your benefits
  • Improved process control and easier quality control thanks to quick and reliable monitoring of product concentration
    • Measuring range up to 2.5 AU or 50 OD (depending on optical path length)
    • Measurement of UV absorption at discrete wavelengths between 254 nm and 313 nm
    • Outstanding filter properties for highest linearity
    • Direct concurrence with laboratory values
    • Integrated reference detector for lamp compensation
    • Gas discharge lamp for long service life and stable measured values
  • FM- and ATEX-approved lamps for applications in the hazardous area
  • Compliance with life sciences sector thanks to hygienic design and FDA- and USP-compliant sealing materials
  • High degree of product safety as SIP/CIP-resistant
  • High product yield thanks to low volume requirements
  • Maximum durability in all applications owing to wide range of materials and process connections
  • Can be adapted to process requirements: Optional air purge ports to prevent the formation of condensate on the optical windows
Measuring principle Light absorption

The measuring principle is based on the Lambert-Beer law.

There is a linear dependency between the absorption of light and the concentration of the absorbing substance:

A = -log(T) = ε . c . OPL
T = I/I 0
T ... Transmission
I ... Intensity of received light at detector
I 0 ... Intensity of transmitted light of light source
A ... Absorption
ε ... Extinction coefficient
c ... Concentration
OPL ... Optical path length

A light source emits radiation through the medium and the incident radiation is measured on the detector side.

The subsequent conversion to absorbance units (AU, OD) is performed in the associated transmitter.

Measuring system

An optical measuring system comprises:

  • Sensor (photometer) OUSAF46
  • Transmitter, e. g. Liquiline CM44P
  • Cable set, e. g. CUK80
  • Assembly OUA260
