Product Overview
The HORIBA Aqualog is a simultaneous absorbance and fluorescence spectrometer specifically designed for the rapid characterisation of dissolved organic matter (DOM) in water. The Aqualog combines UV-Vis absorbance with excitation-emission matrix (EEM) fluorescence in a single measurement, generating complete molecular fingerprints of water samples in under a minute.
The Aqualog is used in water quality monitoring, environmental science, drinking water treatment, wastewater management and oceanography for applications including source tracking, treatment efficacy assessment and organic contaminant detection. Its patented A-TEEM technology enables quantitative multi-component analysis without chromatographic separation.
