Drinking Water Analysis Application Notes

  1. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS
    10/1/2014

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

  2. ABB Aztec 600 Manganese Analyzer Optimizing Manganese Removal Efficiency
    11/15/2017

    The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.

  3. Application Note: Water Flows From The Golden Hills Of California

    Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI
  4. Technical Note: Using 3M Liqui-Cel Membrane Contactors To Solve Resistivity Problems In A High Purity Water Loop
    1/30/2009

    Pureflow, Inc. is a Southeastern-based expert in designing complete water treatment systems as well as providing value-added solutions for fixing operational issues in existing systems. Pureflow teamed up with Membrana to help solve an operational issue at one of their customer’s facilities. By Membrana

  5. Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria
    2/3/2011
    A search for algal toxins in North Carolina reservoirs has evolved into an ongoing early warning system for three important drinking water reservoirs—which serve two large cities—and yielded a greater understanding of the dynamics of blue-green algae, or cyanobacteria, in the state’s reservoir system.

  6. Preliminary Assessment Of Water Quality In Riviera Grise Near Port-Au-Prince, Haiti
    10/17/2012

    The Riviera Grise drains water from the Cul-de-Sac watershed, Haiti, which covers most of the rural areas along the flood plains and areas that extend into steep hillsides. It also covers urban areas of Port-Au-Prince, the capital city of Haiti.

  7. Organics Monitoring (TOC)
    2/1/2013

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.

  8. The Importance Of Measuring Total Organic Carbon
    4/13/2017

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

  9. 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.

  10. 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.
