Fusion Total Organic Carbon (TOC) Analyzer
10/16/2014
The Fusion Total Organic Carbon (TOC) Analyzer utilizes UV Persulfate oxidation allowing superior carbon liberation from even the most challenging matrixes. Low-end sensitivity is achieved from a Non-Dispersive Infrared (NDIR) detector. The Fusion Total Organic Carbon (TOC) UV Persulfate Analyzer offers more flexibility, intelligence and user friendliness making this analyzer ideally suited for the most demanding laboratory needs.

Purge and Trap Background
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated. -
Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications
8/2/2015
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
5/31/2011
Total bound nitrogen (TNb) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TNb measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water
4/13/2017
In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.

New Water Turbidity Measurement Technology — The US Experience
2/3/2017
The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.
