Fluorescence – Water Treatment Plant Analyzer - Aqualog

A better, faster and economical method for monitoring organics

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 Solo™ package from our partner, Eigenvector Research, Inc.

NEW A-TEEM™ technology

A-TEEM technology uses absorbance, transmittance and EEM data to fingerprint molecules with high specificity and ultrahigh-sensitivity at a 6 million nm/min emission scan rate!

All colored molecules exhibit unique molecular absorbance and transmittance spectra; many colored molecules also exhibit unique fluorescence excitation and emission spectra that can be measured as an excitation-emission matrix (EEM). Simultaneously combining Absorbance–Transmission and EEM is a new technique (A-TEEM) that provides a distinct molecular fingerprint with numerous potential applications.

Aqualog combines an ultrafast CCD that’s up to 4,000 times faster than traditional PMT-based fluorometers, with our new A-TEEM technology so you can easily and effectively identify, quantify and understand individual organic compounds in complex mixtures in minutes. A-TEEM has already proven in many cases to be more effective in protein, vaccine, wine and water research, quality and process applications than HPLC and vibrational spectroscopy.

NEW Automatic Sipper Accessory

New for our Aqualog®  A-TEEM™ spectrometer, the Aqualog automatic sipper accessory handles sampling from a single source, in addition to dispensing rinsing solutions, detergents and controlling reverse-flow drainage The 4-sample changer unitconnects to the main sipper unit to enable sampling of up to 4 sources.

The sipper offers convenient installation and operation, with built-in automatic cleaning, leak detection and protection.  It is fully integrated into the new Aqualog 4.0 software for batch analysis and has a variety of uses in water, pharmaceutical, beverage phenolics and many other applications.

When used at a water treatment plant, the sipper and four channel accessory enable the Aqualog to automatically extract and monitor raw, settled and finished water samples. Each sample changer unit is compatible with overflow and filtration devices, serving up to 4 independent water treatment plant sources.

Fast & Non-invasive Determination of Skin State
Biological tissues contain chromophores that absorb light, as well as fluorophores that absorb and reemit light (fluorescence effect). Light absorption depends on the chromophores’ content and their distribution within the organic matter.
Insulin Structure and Stability Assessment
Insulin Structure and Stability Assessment
Stability and aggregation of insulin are studied using simultaneous fluorescence excitation emission matrices (EEMs) and UV-Vis absorbance spectroscopy [1]. Insulin is a protein-hormone, produced by the pancreas and is necessary for basic metabolic processes. The different types of commercial insulin therapeutics generally fall into two categories: short-acting and long-acting insulin. The difference between some short-acting and long-acting insulin is, in some cases, only one to three residues in the protein sequence.
