Drinking Water Measurement Application Notes

31. Water Determination In Liquefied Petroleum Gas Using GC BID And Ionic Liquid Column Watercol™ 6/28/2018

    Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.

32. 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.

33. 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.

34. Flow Meter Enhances Chlorination System Performance For Municipal Water Department 12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.

35. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money 12/1/2017

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

36. Harmonics Reduction Methods 4/17/2017

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

37. VFD Energy Savings For Pumping Applications 4/6/2017

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

38. Protecting Pumps From Dead Head Conditions 4/6/2017

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

39. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives 4/1/2017

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

40. Advances In Paper-Based Devices For Water Quality Analysis 2/22/2017

    Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
