  1. Ultra-Portable, Laser-Based Gas Analyzers For Environmental And Industrial Applications

    Los Gatos Research is a member of ABB Group and produces leading-edge laser-based gas analyzers. This video features their ultra-portable gas analyzer and describes its capabilities.

  2. Modified Laser Absorption Spectrometer Permits Syringe-Sample CH4 Measurements In Peatlands

    Peatlands represent a large source of atmospheric methane, a greenhouse gas with the potential for a much greater impact on climate change than carbon dioxide.

  3. Measurements Of Multiple Greenhouse Gases Using Novel Laser Absorption Based Analyzers

    Scientists concerned with climate change study the origins and effects of greenhouse gases in the atmosphere – gases that trap heat and cause a rise in global temperatures. Carbon dioxide generated by the burning of fuels is a well-known greenhouse gas. Another greenhouse gas is methane (CH4). In fact, methane has about 20 times more heat-trapping capability than equal amounts of carbon dioxide.

  4. Monitoring CO2 Sequestration Leakage Via Laser-Based Spectroscopy In The Field

    Efforts to minimize the heat trapping effects of greenhouse gases on climate include purifying, capturing, and storing (sequestering) carbon dioxide in geologic formations. These formations include oil and gas reservoirs, saline aquifers, and coal seams. It is critical that the stored carbon dioxide does not leak back into the atmosphere too rapidly, and carbon sequestration sites are equipped with sensors to detect carbon dioxide leaks.

  5. Measuring Methane Accumulations From Small Lakes Via Eddy Covariance

    While wetlands are responsible for a relatively large percentage of methane emissions, some scientists have suggested that lakes and other bodies of water may also contribute heavily. Small lakes have higher methane fluxes per unit area than large lakes. Recent estimates have significantly increased the number of small lakes worldwide. New research efforts can help to determine the scope of these emissions.

  6. Trace HCL Measurements In Coal-Fired Power Plant Emissions Using Cavity Enhanced Laser Absorption Spectroscopy

    Regulations recently promulgated by the Environmental Protection Agency (EPA) require qualifying power and cement plants to monitor and control hydrogen chloride (HCl) emissions. These regulations call for HCl concentrations to be below 1 ppm for power plants and 3 ppm for cement plants.

  7. ABB Publishes Swirl Meter Application Guide

    ABB’s Measurement Products’ business announces the availability of a 28-page application guide for Swirl flowmeters.
