  • Hydraulic Fracturing and the Environment Whitepaper - Analytical and Measuring Instruments

    The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...

  • Analytical Devices for the Measurement of Water Vapor in the Natural Gas Process and Transmission Industry

    ABSTRACT The determination of water vapor (and water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to freezing and corrosion of plant and equipment. There are a number of ways of determining the water vapor ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • Optimisation of analytical method for estrogen in surface water and primary risk assessment in South Creek

    A very non-polar sorbent, polystyrene-divinyl-benzene (brand: biobeads supplied by BioRad, with 30∼50 mesh) was tested for its extraction efficiency of four target compounds, estrone, estradiol, ethynylestradiol and estriol, from larger volumes (8 l) of water samples. To achieve adequate sensitivity of instrumental analysis by GC/MS, an improved estrogen derivatisation method was developed. For ...

  • 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 ...
