Laser detection solutions for water-quality monitoring - Monitoring and Testing - Water Monitoring

The technology of Spectral Fluorescence Signatures (SFS) is a very sensitive and selective tool to monitor many industrial processes on site and in real-time. The SFS analyzer series – SFS-Scanner and Instant Screener spectrofluorometers - are capable of detecting target substances even in complex mixtures without any pre-treatment of the samples.

The SFS-Scanner field portable spectrofluorometer (also available as a benchtop version) measures low concentrations of organics in water such as oil, phenols, humic and fulvic acids, benzene, toluene, xylene, polycyclic aromatic hydrocarbons (PAHs), and phytoplankton.  

The Instant Screener is a more universal spectrofluorometer, which utilizes SFS to measure organic compounds in optically dense liquid and solid samples. Due to this feature it is well applicable to monitor production processes and provide quality control in food and pharmaceutical industries. 

Our SFS-analyzers have been successfully applied to water-quality monitoring at intake, liquid-control during production processes and wastewater assessment before discharge - ensuring that products and processes start safe, meet standards and remain safe at critical points throughout production.

Recently there were developed applications for monitoring Polycyclic Aromatic Hydrocarbons (PAHs) in edible oil, as well as applications for quality control in distilling alcohol, optimisation of beverages production and milk and meat processing.  

Featured capabilities of SFS include:

  • rapid detection & identification of organics
  • no reagents or sample treatment
  • real-time sample analysis or continuous, online monitoring
  • automatic, unattended operation
  • programmable thresholds
  • alarm trigger / process shut down (“smart-pipe”)

SFS can be seamlessly integrated to streamline many OEM offerings wherever fast, reliable, cost-effective, on-the-spot analysis of organics in water environments.
