    Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS

    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.

  • In Pursuit Of The Perfect Glass Of Water
    In Pursuit Of The Perfect Glass Of Water

    Water, classified as one of the basic elements since ancient time, is so essential, so simple, yet can be so challenging to deliver at high quality in high volumes. Pursuing the “perfect” glass of water involves two major influences: 1) regulatory requirements and 2) aesthetics or organoleptic quality (i.e., taste, odor, appearance, etc.). To start, it helps to be blessed with the good fortune of good source water quality, but beyond that it comes down to how a water utility treats and “polishes” the final product. Even for utilities not totally obsessed with garnering national taste-test honors, here are several factors to be considered when searching for the perfect glass of water, and the role that turbidity measurement can play in them.

  • Turbidity 101: What It Is, And Why It Is So Important
    Turbidity 101: What It Is, And Why It Is So Important

    Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.

Here is a quick overview of turbidity’s relationship to drinking water compliance standards and some tips for keeping a water treatment process in balance.

  • Bringing An END™ To RO Brine And Difficult Brackish Water Treatment
    Bringing An END™ To RO Brine And Difficult Brackish Water Treatment

    Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

  • Choosing Contract Services For Proactive Instrumentation Maintenance
    Choosing Contract Services For Proactive Instrumentation Maintenance

    In an industry faced with around-the-clock operations and penalties for noncompliance with regulatory standards, it can be easy to lose track of periodic maintenance requirements whose impacts might not be noticeable until it’s too late. Ignoring the influence that measurement and analytic equipment maintenance can have on water treatment plants (WTPs) or wastewater treatment plants (WWTPs) can be costly. Fortunately, equipment suppliers who bundle after-sale services tailored to WTP and WWTP needs offer new opportunities for instrumentation users to stay ahead of the curve in terms of timely response to changing performance.
