  • GC-MS/MS Analysis of Pesticides in Drinking Water

    According to Japan’s list of drinking water quality control substances, pesticides are included as supplemental items subject to analysis. Designed to complement the standards, the Ministry of Health, Labour and Welfare encourages water utilities to monitor pesticide levels and achieve specified targets. Among the 102 listed pesticides, 84 are simultaneously analyzed using solid-phase ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Analysis of impurities in ultrapure water by dynamic reaction cell ICP-MS

    Ultrapure Water (UPW) is used for the cleaning of instruments and containers in trace analysis and for dilution of samples. The analysis of impurities in UPW requires increasingly lower levels of detection and higher instrument productivity. SEMI Standard F63-03091 specifies a maximum contamination for metals of 0.02-0.1 ppb for each element for ultrapure water used in semiconductor processing. ...

  • Analysis of Haloacetic Acids in Tap Water Using LC/MS/MS

    Haloacetic acids are produced as by-products of chlorination in the water treatment purification process. Three haloacetic acids, monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), and trichloroacetic acid (TCAA), are subject to water quality standard for drinking water with established limits (MCAA: 0.02 mg/L, DCAA: 0.04 mg/L, TCAA: 0.2 mg/L) by Japan Ministry of Health, Labour and ...

  • Oil-In-Water Analysis. Verification of Particle Counter results by optical microscopy

    For my research work, which concerns separation of liquid/liquid dispersions, I selected the Spectrex PC2200. It covers the whole range of droplet sizes which are of interest, i.e. from 0.5 to 100 microns. The procedure for analysis is very simple and results are obtained in less than a minute. This makes the Spectrex instrument very handy for use in the lab as well as for field measurements (A ...

  • TOC Analysis: The Best Tool in a Drinking Water Facility`s Toolbox

    Total organic carbon (TOC) has become an important water quality analysis tool for drinking water plants in recent years due to its link to disinfection byproducts (DBPs). TOC alone is not harmful, but upon its reaction with a disinfectant can produce harmful byproducts. However, TOC’s relevance in drinking water ...

  • Today’s TOC; Tomorrow’s DBPs - How total organic carbon (TOC) analysis relates to disinfection byproducts (DBPs) such as Trihalomethanes (THMs) and the corresponding China standards for drinking water quality

    “A clean drinking water supply has become a national priority for China,” according to the Chinese State Press and Premier Wen Jiabao. Municipalities throughout China are challenged to balance the risk of microbial pathogens and by-products from the disinfectant used to destroy these microbes. The byproducts, called Disinfection Byproducts (DBPs), form from the interaction of the naturally ...

  • Water Quality Changes During 500-Year Flood Controlled with Sievers TOC Analyzer

    During September 20–21, 2009, over 18 inches of rain fell in Acworth, Georgia. The U.S. Geological Survey called this an epic 500-year flood for the area and one of the worst floods in the U.S. during the past 100 years. The flooding caused the local drinking water treatment plant, Cobb County-Marietta Water Authority, to see a rapid decrease in the Allatoona Reservoir source water ...
