  • Laser induced release of encapsulated noble gas in SCHOTT receiver

    Thermo oil based parabolic through technology is limited to operational temperatures close to 400°C due to the decomposition of the heat transfer fluid and accompanying hydrogen permeation into the vacuum annulus. The presence of hydrogen in the annulus leads to an increase of thermal losses and a decrease in thermal efficiency. In order to overcome this so-called ‘hot tube ...

  • Improved HF monitoring in Primary Aluminium Smelters with Laser Gas Detectors

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Concerns for worker safety and ambient air quality require that HF be monitored at several locations in smelters. Historically, a variety of methods have been used for HF monitoring. Cassette samplers and wet chemistry techniques, coupled with complex and expensive ...

  • 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 ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • PureAire Oxygen Analyzer for 3D Printers: How Argon is used and Why O2 Detection is Required

    Thanks to new technologies, the 3D printers that have been used to create plastic three-dimensional objects can now print metal. Titanium 3D printing is possible thanks to a technique called DMLS, or Direct Metal Laser Sintering. While the potential to use titanium 3D printing is groundbreaking for many industries, the new advances could pose a health hazard if volatile gases used in the printing ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...
