Photolab®7600 UV-VIS

Innovative and well-proven - Optical reagent-free (OptRF) and routine analysis!
The spectrophotometer photoLab® 7600 UV-VIS offers the universal use from well-proven routine analysis to spectral analysis with pioneering procedure OptRF for reagent-free measurement of COD, Nitrate and Nitrite. Furthermore, important parameters such as UVT and SAC as well as comprehensive color measurement are supported. Being light-weighted and optionally powered by standard car battery, photoLab® 7600 UV-VIS can be operated On-site easily.

  • Faster than the fastest digestion.
  • No costs, as no reagents or chemical required.
  • Check of measurement range.
  • Environmentally friendly and no health hazards.
For the standard parameters COD, Nitrate and Nitrite, a spectrum of UV- range is evaluated by means of complex algorithms wich are based on reference spectra. The result is put out directly as concentration reading, without the use of reagents. No potassium dichromate, no digestion - for quick testing. The composition of the water (matrix) is important for this value determination, since water is not equal to water.

The OptRF- methods are currently being developed for sewage plant outlets. They can be optimized for the respective municipal waste water matrix by user calibration via reference values performed with standard procedures like test kits. Depending on the composition of surface waters, the methods can be used here as well after testing and verifying with reference procedures.
