The only Site Specific Calibration UV/Vis Spectrometer System
The intelligent spectral analyser 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.
The detection is not limited to a few bands, instead the whole spectrum from ultraviolet to near-infrared (200- 720nm) is detected and analysed. Solutes, suspended matter and other water properties can be characterised 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.

Product Variants
The ISA UV/Vis Spectrometer is available in different variants. The ISA complete systems in combination with a BlueBox TS measuring- and control system allow for a stand-alone operation. GO Systemelektronik also offers a portable mobile version for flexible applications.
The battery-powered system is designed for an autonomous operation on-site. ISA Module variants can be integrated into existing measuring systems and enable their expansion through the CAN bus interface. Depending upon the application requirements the ISA UV/Vis Spectrometer is available either as an in situ measuring head for immersion measurements or as a flow through fitting.
