Compact, Universal Spectrophotometric Sensor - ISIS II

ISIS II is a full-range UV-visible spectrometer probe which can be fully immersed in a tank, pipe or process stream and measures continuously, with high stability and almost no maintenance.

Spectral information between 200 – 710 nm and in the Near InfraRed region* is transmitted through an optical fibre to the BlueBox, where it is transformed and used to calculate the concentration of nitrate, suspended solids, organic compounds, DOC, COD, SAC and other para-meters.

The probe is exceptionally easy to install and operate and offers enormous cost savings.

UV-Vis Spectrometer*

* (extended Near InfraRed range available soon)

ISIS II Area of applications

Uses the full UV-Vis-range (200 - 710 nm).
Using existing calibrations for standard parameters
Creating specific calibrations by multivariate chemometrics e.g for dyes, detergents, surfactants, turbidity, suspensions, emulsions and
many other types of material.
Easy adaptation to various samples with different pathlengths.

Nitrate

For NO3/NO3-N measurements

Range: 0.1 - 100 mg/l NOx_eq (extendable)
Accuracy: ± 5 % rel. of full scale*
20 sec/measurement

Solids

Turbidity derived from spectral information correlates with solids even under difficult conditions. The character of the particles is accounted for i.e. particle size, colloids, bubbles.

Organic Carbon Parameters (natural and drinking water)

Correlation with DOC and COD in natural and waste water, drinking water, process water.

DOC (natural and drinking water)

Range (mg/l): 0.01 - 50 (extendable to 500)
Accuracy: ± 5 % rel. of full scale*

COD

Range (mg/l): 10 - 100
Accuracy: ± 5 % rel. of full scale*
20 sec/measurement

* Resolution and accuracy of applications depend on the quality of the reference analytics and the stability of the water matrix.
