  • Diffuse reflectance spectroscopy using a handheld FTIR

    As has been previously discussed (1), FTIR spectroscopy is emerging as a technique that can be effectively used for applications and/or in locations that heretofore would be considered too demanding. The development of portable FTIRs, and more recently handheld FTIRs, is significant because it enables this powerful analytical technique to solve problems for a whole range of new applications, both ...


  • Pumping Ions – An Exercise in Engineering Sensitivity Into the Xevo TQ-XS Mass Spectrometer

    The challenge: Create the most sensitive mass spectrometer for quantitative analysis. That’s a tall order for any design engineering team. When given that assignment for a next-generation, tandem quadrupole mass spectrometer, our design engineers first spoke to those for whom analytical sensitivity means the most: scientists doing quantitative studies for ...

  • Understanding the impact of snow`s reflectance

    To help improve the accuracy of climate models, an international team involving the National Physical Laboratory (NPL) has measured the reflectance of rough, snow-covered surfaces at large solar zenith angles. A crucial factor in climate models is Earth's albedo, which is the reflectance of Earth's surface: dark ground has a low albedo, reflecting little light, whereas ice and snow have a high ...

  • TVOC measurement for LEED/green building evaluation

    Total Volatile Organic Compounds (TVOC) may be evaluated when building designers/managers are pursuing the Leadership in Energy and Environmental Design Green Building Rating System for New Construction (LEED-NC) EQ Credit 3.2. The latest LEED-NC guidance document specifies that the maximum allowed concentration of TVOC measured in a building (post construction, pre-occupancy) is 500 µg/m3; the ...


  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...
