Aqualog® - Our compact, Benchtop Fluorometer for CDOM

Overview

Aqualog

New Datastream Dashboard Software

Aqualog is the only instrument to simultaneously measure both absorbance spectra and fluorescence Excitation-Emission Matrices. EEMs are acquired up to a 100 times faster than with other instruments. Dedicated software automates traceable Quinine Sulfate Unit calibration and correction of inner-filter effects and Rayleigh and Raman scattering lines, enabling rapid export to modeling algorithms like PARAFAC.

multivariate analysis - AqualogAqualog now offers new deep UV absorbance and fluorescence excitation from 200 nm, in addition to a fully automated sample queue tool to facilitate continuous data acquisition, analysis and export for immediate multivariate analysis with the Solotm package from our partner, Eigenvector Research, Inc.

The NEW Aqualog® Datastream Dashboard facilitates completely automated analysis and reporting of a wide range of organic matter parameters that are critical for managing and optimizing the drinking water treatment process. The Datastream parameters have been selected to specifically target disinfection by-product issues, algal issues and other contamination components
