Drinking Water Application Notes

  1. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water 4/5/2013

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

  2. Application Bulletin: Reverse Osmosis 3/19/2008

    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

  3. LC-MS Analysis Of PFAS Compounds In EPA Methods 537.1, 533 And 8327 11/4/2021

    The Ascentis Express PFAS HPLC column is designed for the separation of novel and legacy PFAS as per recent EPA methods. A specific PFAS delay column prevents background PFAS contamination from interfering with sample results in quantitative LC-MS methods.

  4. Drinking Water Testing By Ion Chromatography Using Ultrapure Water 9/29/2022

    This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

  5. 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.

  6. Air/Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency 12/15/2017

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

  7. The Basics: Keeping Our Water Clean Requires Monitoring 4/30/2014

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  8. Alcoholic Beverage Fusel Alcohol Testing With Static Headspace 9/2/2014

    A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

  9. Optimization Of Water Treatment Using Zeta Potential 5/27/2020

    Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic.

  10. 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.
