UV/Vis Spectrometer System

The intelligent spectral analyzator ISA provides the simultaneous acquisition of multiple parameters with only one sensor in a small form factor. This compact UV/VIS sensor provides both standard water quality parameters and additional substances and water properties applying modern chemometrical methods.

  • Description
  • Technical specifications

The detection is not limited to a few bands, instead of the whole spectrum from ultraviolet to near-infrared (200-
720nm) is detected and analyzed. Solutes suspended matter and other water properties can be characterized
thoroughly. This is not limited to common values like e.g. nitrate, organic carbon (TOC) or chemical and biological oxygen demand (COD, BOD) since modern chemometrical methods are permitting the assay of various other components.

The calibration monitoring feature based on a spectral quality index (SQI) is a new technology introduced to absorption spectroscopy by Go-Systemelektronik. This allows an automatic adaptation to water matrix
variances. With this, there is a significant increase in measurement reliability and with this a lower risk of false alerts in water monitoring systems. Another unique feature is the possibility to quickly mechanically adjust the optical path length, without special tools.

THE SYSTEM IS DESIGNED FOR THE CONNECTION OF UP TO 200 SENSORS AND ACTUATORS.
