  • 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 ...

  • Low level moisture measurement in Natural gas using a Lunable diode laser absorption spectroscopy (tdlas) based laser case study

    Introduction The measurement of water vapor in natural gas has long been of industrial importance, and has been addressed by a variety of analytical techniques over the years. Chief among these techniques has been the quartz crystal microbalance (QCM) based analyzers. The QCM technology is still the workhorse for production and pipeline applications, and the technique is considered by most ...

  • Hiden ESPion plasma probe measurements on a hollow-cathode based large-volume plasma source

    Vacuum-based surface engineering and coating processes require plasma sources generating a high charge carrier density in order to achieve enhanced sputter and activation effects. Fraunhofer FEP is providing a hollow-cathode based plasma source, which produces homogeneous large-volume plasmas of up to 1 m3 with maximum plasma densities of more than 1012 cm-3 at chamber pressures between 0.1 and ...

  • Electrochemical biosensors for environmental monitoring

    The challenge for the monitoring of environmental hazards such as pollutants, herbicides, pesticides and toxins caused by expanding industrialisation and application of new intensive agricultural technologies is to develop efficient tools that offer precision, sensitivity, and speed and ease of operation in situ and avoid consequently risks for both human and environmental health. In this ...

  • Theory of nonequilibrium transient transport in nanostructures

    We present a brief review of time dependent quantum transport theory for analysing nanoelectronic devices. We focus on both theoretical and numerical techniques developed recently for calculating time-dependent current flowing through noninteracting phase-coherent conductors connected to external leads, in response to external time dependent bias voltages. For sharp step- and square-shaped ...

  • McClellan AFB comparison of 6 no-purge groundwater samplers

    This report describes the activities and results of a field demonstration of six different diffusion and grab groundwater sampling devices at the former McClellan Air Force Base (McClellan), located in Sacramento, California. Analytical results from these samplers are compared to ‘baseline’ analytical results from samples collected using conventional (low-flow and three-casing-volume purge) ...

  • Success story: How we solved the bench space equation in a lab!

    Problem Overview Nowadays laboratories are equipment intensive and require as much bench space as possible. Recently, our company has being challenged by a lab manager of a primary Italian food industry to find a solution for his saturated lab bench. Among several devices, about 13 GC-FID’s are working with several gas generators. The initial choice for having on-site gas ...

  • Analysis of impurities in nitric acid by dynamic reaction cell ICP-MS

    Nitric acid (HNO3) is widely used in the semiconductor industry. Semiconductor devices are currently being designed with smaller line widths and are more susceptible to low level impurities. In more critical processes, the impurities in HNO3 need to be monitored for continuous performance at desired and achievable levels of quality. SEMI Standard C35-0708 specifies the maximum concentration of ...

  • Alkylphenols in atmospheric depositions and urban runoff

    A sampling campaign was conducted in order to determine alkylphenol (AP) concentrations in stormwater as well as potential AP sources in suburban environments. An analytical procedure was developed to quantify APs in bulk atmospheric deposition, building runoff, road runoff and stormwater. Both nonylphenols and octylphenols could be quantified in each sample. Median stormwater concentrations ...

  • Searchline excel performs through water curtain

    One of the primary advantages of the Searchline Excel is its relatively high immunity to rain and fog. A field test conducted recently by BP and DMSI at the Texas A&M Fire School provided some further evidence of just how good Excel is at ignoring water in its optical path. The Fire School at Texas A&M University maintains a LNG test and training site that has long been equipped with Searchline ...
