    In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

  3. Defining Drinking Water Plant Backwash Profile Using The SOLITAX™ Sc Suspended Solids And Turbidity Sensor
    6/7/2013

    Today’s drinking water plants have many challenges to meet as they produce water for a fast-growing and increasingly demanding population.

  4. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution
    9/29/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  5. 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.
  6. How To Read An Encoder
    9/13/2013

    The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.

    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

  9. The Basics: Testing RO Quality
    4/28/2014

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.

  10. Network Monitors Water Quality In Shale Gas Drilling Region
    9/2/2011
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars.
