81. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS 6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

82. Ultrapure Water For Determination of Toxic Elements In Environmental Analyses 4/10/2018

    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.

83. Hemodialysis Patient Health 10/29/2021

    Controlling dialysate quality is critically important to hemodialysis patient health. Complications as minor as nausea and fatigue or as severe as metabolic acidosis and sepsis can result if dialysate composition is incorrect. All the factors that ultimately affect dialysate composition must therefore be carefully monitored and controlled: proper proportioning and mixing of concentrates with water; the quality of water mixed with concentrates to form dialysate; and the quality of water used in the reprocessing of hemodialyzers, system maintenance and disinfection.

84. 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.

85. Spectrophotometry Theory And Practice 8/18/2026

    Spectrophotometry is one of the foundational analytical techniques used to quantify substances in solution by measuring their absorption of light. Understanding the relationship between electromagnetic radiation, wavelength selection, and absorption behavior is critical for developing accurate analytical methods and generating reliable measurement data.

86. Waterworks Joints 101 10/30/2025

    There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

87. 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.

88. Bringing Efficiency And New Confidence To BOD₅ Analysis 2/4/2013

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

89. Leak Detection On Water Distribution Network Using Clamp-On Flowmeters 5/22/2023

    A global engineering company realized that their leak identification methods were time consuming and expensive, and so began to explore alternative solutions, such as ultrasonic flow meters. 

90. 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.
