Drinking Water Measurement Application Notes

  1. 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.

  2. Accurately Measuring Network Leakage
    6/26/2015

    The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.

  3. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood
    4/20/2015

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

  4. Determination Of Pesticide Residues In Tea
    4/10/2015

    In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

  5. Determination Of Hexanal In Foods Utilizing Dynamic Headspace
    4/9/2015

    Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

  6. Validation Of Environmental Water Methods On One System
    4/6/2015

    Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.

  7. (E)-2-Nonenal In Beer
    4/5/2015

    Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.

  8. Analyzing Total Organic Carbon In Sea Water
    4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  9. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    10/16/2014
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  10. Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution
    10/16/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
