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, which simultaneously measures 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 tests make the Aqualog a turnkey tool for water research.
