  • Arctic Polar Research - A Global Responsibility

    Due to climate change and geopolitical trends, the Polar Regions (particularly the Arctic) are increasingly becoming the focus of scientific, political, and economic interests. Much of the global climate is driven by forces that originate in the Arctic. The Arctic sea ice is receding faster than climate models have predicted, and the movement of freshwater into and around the Arctic plays an ...

  • Understanding Oil-in-Water Instrument Specifications

    The measurement capabilities of oil-in-water analysis methods are described by several analytical figures-of-merit. Examples are: Range (Linear and Dynamic) Limit of Detection (LOD) Limit of Quantification (LOQ) Precision (Repeatability and Reproducibility) Sensitivity Accuracy Response Time Some or all of these are often specified by customers in the bid packages issued when selecting a ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...

  • Rainy Day Session Instruments

    Rainy Day Session Instruments Rain and melted snow in the United States winter can cause runoff.  Such winter runoff causes the movement of soil or at least cloudy turbid water. This had been known to occur on native undisturbed lands. However, with the growth of the population, we see more and more development ...

  • Innovations in Bench Testing of Waste waters

    Wastewater management in developing countries throughout the world is in a state of crisis. It is estimated that 2.6 billion people worldwide live without adequate sanitation. Resources are scarce, previous management systems have failed, and traditional techniques and solutions are not immediate enough, too expensive, or simply inefficient. Discussion with regards to OI Analytics Instrumentation ...


  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • TOC System Suitability Test for Sterile Water

    The United States Pharmacopeia (USP) specifies that total organic carbon (TOC) content be used for management of organic impurity values permitted in bulk purified water, water for injection, in addition to sterile purified water and sterile water for injection. According to USP, TOC analyzers to be used for sterile water must satisfy the TOC system suitability test using test water ...

  • Why instrument hire makes occupational safety sense

    Background Decisions concerning the acquisition of occupational safety monitoring instrumentation are often made by operational staff that may not have visibility of the full financial implications of their choices. The following article will examine the factors affecting these decisions and explain why a strategic decision to hire instrumentation can deliver substantial and wide-ranging ...

  • 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 ...

  • Introduction to Environmental Testing in the USA

    Environmental laboratories practice “applied analytical chemistry” by analyzing samples using a list of potential contaminants to determine how much, if any, of the contaminant is present. These contaminants, the methods used to analyze for them, and the maximum amount of contaminant allowed in the sample are defined by regulation. This paper provides an overview of ...

  • A Biaxial Apparatus for Testing Soils

    A biaxial compression apparatus for investigating shear-band formation and growth in dry and water-saturated sand and clay specimens is described. This apparatus is a modification of the device designed by Vardoulakis and Goldscheider [1] for testing planar shear banding in sands. The modifications involve improved axial load guidance, low friction linear bearing, and enhanced load and ...

  • Population-based study of intra-household gender differences in water insecurity: reliability and validity of a survey instrument for use in rural Uganda

    Hundreds of millions of people worldwide lack adequate access to water. Water insecurity, which is defined as having limited or uncertain availability of safe water or the ability to acquire safe water in socially acceptable ways, is typically overlooked by development organizations focusing on water availability. To address the urgent need in the literature for validated measures of water ...

  • Why is Calibration of Water Quality Testing Equipment so Important?

    The calibration of water quality testing equipment is as important as the tuning of a musical instrument. When people find out I’m a chemist, the first thing they ask me is, “Are you Walter White?” (This shows you the kind of people I typically run into). The second thing they ask me is, “Why is calibration so important?” Simply stated, calibration is how we adjust ...

  • New TOC sensor wins Gold IBO award for portable instrument design

    In 2006, the USEPA singled out the distribution system as the most vulnerable component of a utility’s drinking water system. In response, many waterworks are taking a closer look at how they may protect the public’s drinking water. One option is to place online water quality panels throughout the distribution system to detect a change in the baseline water quality. The cost of implementing a ...
