Spectrofluorometer AquaLog

A compact, benchtop fluorometer for CDOM

  • TE-cooled CCD fluorescence emission detector for rapid data acquisition up to 100 times faster than any other benchtop fluorometer;
  • water Raman signal-to-noise ratio: 4 000:1;
  • the only true simultaneous absorbance-fluorescence system available.

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.

AquaLog 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.

Excitation Source
Standard: 150W vertically mounted ozone-free Xe source. Extended-UV: 150W vertically mounted xenon arc lamp.

Excitation Monochromator
Aberration corrected double-grating excitation monochromator for low stray-light performance.

Emission Spectrograph
Aberration corrected emission spectrograph with TE cooled CCD for rapid emission measurements.

Reference detector to correct both absorbance and fluorescence detector signals. Absorbance detector for simultaneous excitation and emission data acquisition.
