Analytical Instruments Application Notes

  1. Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    3/3/2015

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.

  2. 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.
  3. 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.

  4. 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.

  5. 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.

  6. Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution
    9/24/2014

    Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

  7. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution
    9/17/2014

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

  8. Reducing Total Phosphorus In Water Resource Recovery Facilities
    9/10/2014

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

  9. 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.

  10. Wastewater Treatment Facility Complements On-Line Monitoring With Automated Control
    7/15/2014

    The Minnesota River Valley Public Utilities Commission (MRVPUC) provides wastewater treatment for the City of Le Sueur and the City of Henderson in south-central Minnesota. A significant factor facing the utility is the highly varying phosphorus load that challenges operators to meet the utility’s annual average discharge limit of 1.0 mg/L total phosphorus.
