The new Aqualog measures CDOM (colored dissolved organic matter) in water. This instrument simultaneously measures both absorbance spectra and fluorescence excitation-emission matrices (EEMs). It features a 150 W xenon lamp, a double-excitation monochromator for stray light rejection, a photodiode for absorbance spectra, and a TE-cooled CCD for collection of rapid emission spectra.

PRESS RELEASE
AqualogTM measures CDOM (colored dissolved organic matter) in water 100 times faster than previous fluorescence methods
Identifying and quantifying natural and man-made colored dissolved organic matter components is a crucial problem in understanding water quality. This measurement requires the collection of both the fluorescence and absorbance spectra of the sample. To address this need, HORIBA Scientific introduces the Aqualog, the only instrument to simultaneously measure both absorbance spectra and fluorescence Excitation-Emission Matrices (EEMs). Instrument features include: a 150 watt xenon lamp, a double excitation monochromator for superior stray light rejection, a photodiode for absorbance spectra and a TE cooled CCD for collection of rapid emission spectra. Easy to use software and a full suite of NIST traceable validation test make the Aqualog a turnkey tool for water research.
