    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 ...

  • Argon and Nitrogen in Glove Boxes and Blanketed Chambers case study

    Application Moisture is measured in argon or nitrogen when it is used as a blanketing gas in glove boxes and other blanketed applications. Problem The presence of moisture in the blanket gas for a glove box causes serious contamination problems especially when welding or conducting moisture-sensitive chemical reactions. Moisture causes product contamination, ...

  • Hydrogen annealing ovens case study

    Application Moisture is measured in hydrogen annealing ovens. Problem Hydrogen gas is used in annealing furnaces manufacturing stainless steel and other metal parts. High-moisture concentrations in the hydrogen will oxidize the metal, resulting in an unusable product with a surface finish that is too dark. Equipment Any ...

  • Heat treatment of steels and other metals case study

    Application Moisture is measured in the blanketing gases that are used in the treatment of steel. Problem Inert blanketing gases are required during the heat treatment of steels to prevent oxidation of the metal product. At heat-treating temperatures, moisture and oxygen will readily react with the metal to form an undesirable metal-oxide coating on the ...

  • Helium gas for nuclear reactors case study

    Application Moisture is measured in helium gas used for nuclear reactors. The helium is used as a reactor coolant because of its excellent thermal properties and chemical inertness. Problem If the helium becomes contaminated with moisture, it will cause both degradation of graphite rods and an undesired change in the process's heat balance. At worst, a ...

  • Instrument air case study

    Application Moisture is measured in instrument air to ensure that the air is properly dried. Problem Instrument air is used through-out a facility to protect delicate electronics, instruments, and to operate key process actuators. Many instruments also use instrument air to operate various pneumatic operators they might possess. Too frequently, there is ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • The Secret to Quality Food Products

    Quality is everything when it comes to food, and accurate moisture control is essential to quality. Decrease spoilage, wasted products and lost profits by making sure you’re accurately monitoring the moisture content of your food products. Join us July 17-19 in Chicago, IL at the International Food Technologists Annual Meeting & Expo ...

  • Temperature effects on bioremediation of PAHs and PCP contaminated South Louisiana soils: a laboratory mesocosm study

    Goal, Scope and Background. Temperature and soil moisture content are important environmental variables in bioremediation technologies.Optimizing these variables in-situ would enhance andmaintain remediation of hazardous wastes during cold winter seasons or in cold regions and may lead to reduced maintenance and/or cost. The effect of elevated temperature and soil moisture on bioremediation ...


  • Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama

    The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Instant Loss on Ignition Results for Trommel Fines

    Cost-effective compliance with landfill tax regimes Many issues have been raised with HMRC’s proposed Loss on Ignition (LOI) testing regime for landfill taxes, including concerns that tests will take too long to be actionable and will cost too much to perform with any regularity.
