  2. Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability 1/20/2010
    In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
  3. Signet 2774-2777 DryLoc® pH/ORP Electrodes 11/15/2004

    The Signet 2774 - 2777 pH and ORP Electrodes feature a unique foulproof DryLoc® connector with goldplated contacts designed specifically for use with the Signet 2750 and 2760 preamplifiers, sensor electronics, and connectors.

  4. Colorimetric vs Amperometric Technologies 3/9/2026

    Choose the right chlorine monitoring approach by weighing the continuous, reagent-free speed of amperometric sensing against the superior, stable accuracy of batch-based colorimetric analysis, ensuring long-term reliability based on specific site and process requirements.

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

  6. Thermo Scientific Orion Chlorine XP Multiple Parameter Water Quality Analyzer 11/18/2013

    The Thermo Scientific™ Orion™ Chlorine XP™ analyzer measures free, total, and combined chlorine, providing accurate, objective, and fast readings of chlorine in water. It minimizes the need for periodic calibrations and is compatible with all disinfectant processes. The Chlorine XP analyzer utilizes a DPD-based measurement technology that can be configured to use the least amount of reagents while maintaining utmost accuracy.

  7. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants 8/30/2005

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter

  8. Torch Combustion TOC/TN Analyzer 10/16/2014

    Tekmar’s newest addition to the TOC analyzer product line, the Torch, utilizes a patent Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion.

  9. 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.
