Transforming Water Research Applications

The Aqualog^®-Next is an indispensable tool for a wide array of critical water research and environmental applications:

Climate Change & NOM Analysis: Track global colored dissolved organic matter (CDOM) patterns to accurately assess carbon contributions in aquatic environments. The Aqualog was invented to meet the needs of environmental water researchers around the world studying CDOM using fluorescence spectroscopy, dramatically increasing the speed with which fluorescence EEMs are collected and ensuring quantitative dynamic range.
Harmful Algal Bloom (HAB) Monitoring: Detect early indicators of bloom events and understand HAB species distributions and population dynamics through distinct fluorescence signatures.
Drinking Water Compliance: Optimize organic matter removal and mitigate disinfection byproduct (DBP) formation by tracking NOM fluorescence fingerprints.
Membrane Fouling in Advanced Water Treatment: Investigate how treatment designs and operational parameters impact membrane performance in drinking water (including potable reuse) and wastewater.
Petroleum & Oil Spill Detection: Optically detect hydrocarbons at low concentrations and differentiate them from natural dissolved organic matter. This includes support for ASTM D8431 Standard Test Method for Detection of Water-soluble Petroleum Oils (BTEX) by A-TEEM Optical Spectroscopy and Multivariate Analysis.
Air Pollution Monitoring: Analyze ‘Brown Carbon’ sources associated with fossil fuel combustion.
Detecting Toxic Leachates: Identify and quantify toxic leachates from plastics, polymers, and tires.

Key Features for Unmatched Performance

NIST Traceability: Fully compatible with National Institute of Standards and Technology (NIST) standard reference materials for both fluorescence and absorbance measurements, ensuring reliable and comparable data.
Multivariate Analysis Compatibility: Seamlessly supports PARAFAC, PCA, PLS, and other advanced machine-learning models for powerful decomposition, classification, and regression analysis.
Optional A-TEEM™ Direktor Multivariate Analysis Suite: A guided workflow for fluorescence A-TEEM data analysis, including predictive modeling.
DataStream Dashboard: A web-based interface for real-time water quality monitoring and data analysis.
HORIBA Multimodal Predictor (HMMP) Tool: An exclusive Add-In for Eigenvector Inc.’s Solo and PLS toolbox packages, facilitating multivariate regression and discrimination models.
Fast-03 Autosampler Accessory Support: Streamline your experiments with batch configuration, priming, cleaning, and maintenance controls.
