Water Testing

In this application note, the authors present a novel, rapid method for identifying low concentrations of oil contamination in process water using Fluorescence Excitation Emission Matrix (FEEM) combined with Parallel Factor Analysis (PARAFAC). This method allows for quick detection and analysis of oil contaminants in process water, offering a practical solution for industries where timely intervention is crucial.

Recently, A-TEEM (Absorbance–Transmittance Excitation–Emission Matrix) fluorescence spectroscopy has emerged as a rapid and effective alternative for BOD detection.

This application note describes a rapid, sensitive nondestructive disinfection byproducts (DBP) prediction method using patented simultaneous Absorbance-Transmittance and fluorescence Excitation-Emission Matrix (A-TEEM) spectroscopy.

This application note describes the use of the Aqualog for monitoring regulated Dissolved Organic Matter (DOM) and disinfection by-product issues for drinking water treatment.

This study describes the application of simultaneous absorbance and fluorescence excitation-emission matrix (EEM) analysis for the purpose of identification and classification of freshwater planktonic algal species.

Water travels through the environment carrying dissolved organic matter (DOM), made up of various chemical compounds, which have entered the water column from many sources.

The analysis of Br, Cl, and I is possible with ICP-AES at low limits of detection due to an adaptation of the instrument. This adaptation doesn't affect the determination of other elements and will generally improve analytical performance for any elemental lines below 200 nm for example, Pb at 168 nm.

The analysis of brines can be easily performed using the Ultima Expert. Low detection limits are obtained due to the ability of the system to perform the analysis without any dilution thanks to the 3 mm i.d. injector associated with radial viewing and the Total Plasma view that minimize matrix effects and enhance sensitivity. The sheath gas device allows perfect short and long-term stability of the system for routine analysis, without any internal standard, recalibration, or drift correction procedure. Good long term stability allows the use of the best plasma parameters and integration times for enhanced performance.

Global drinking water sources remain prone to carcinogenic petroleum product contaminations due to lack of detection capacity at or before treatment plant intake. The Aqualog A-TEEM method provides a reliable optical detection of these compounds at low quantities discriminating from the highly absorbing and fluorescent backgrounds of natural Dissolved Organic Matter (DOM) components.

ICP-OES is multielement technique that allows for the fast analysis of more than 75 elements on the Periodic Table in a variety of matrices. This application note examines the analysis of six water and animal food samples.
