  • Tracking Down the Greenhouse Gas SF6 with Infrared

    SF6 Gas Detection Development of SF6 Leak Detection • Early systems for detecting SF6 gas emissions relied on a combination of infrared imaging and active CO2 laser illumination. • Called Backscatter Absorption Gas Imaging (BAGI) – A CO2 laser is scanned over the target area – Reflected laser energy is captured by the IR camera

  • Fourier transform infrared spectroscopy quantitative

    Feb 05, 2015Sulfur hexafluoride (SF 6) gas is widely applied as an electrical insulator as well as an arc-quenching medium in gas-insulated switchgear (GIS).Pure SF 6 is a colorless, tasteless, non-poisonous, and non-combustible inert gas, the dielectric strength of which is thrice that of air at atmospheric pressure .SF 6 gas produces minimal decomposition components under normal operation circumstances.Cited by: 20

  • Infrared absorption of SF6 from 32 to 3000 cm−1 in the

    Dec 01, 1988The integrated IR intensities of the v3 and v4 bands of SF6 were measured by Kim et al. (44) using the Wilson-Wells-Penner-Weber method. Integrated IR intensities of SF6 in the v3 and v4 region were also measured by Brodbeck et al. (45). Up to a density of about 0.25 amagat, there was a linear dependence of the integrated absorption with density.Cited by: 65

  • Visualization of air flow using infrared thermography

    A technique to visualize airflow using IR thermography is developed. A trace quantity of sulfur hexafluoride (SF6) gas is injected into the flow field to detect intensity patterns using a scanning IR thermography system with a single 8–13 µm bandwidth detector. Equations that relate the intensity patterns to volume-averaged temperature and SF6 mass concentration are presented.

  • Intermolecular and intramolecular distribution of the

    The vibrational distribution produced in molecular gases by pulsed IR laser irradiation is studied by high time-resolution Raman spectroscopy. Quantitative data are obtained and interpreted for an ensemble of molecules excited during the IR pulse under both collisionless conditions and conditions involving collisions with the buffer gas particles. The energy threshold at which the vibrational

  • Absorption spectra of atmospheric gases in the IR, visible

    2. Gaseous absorption in the IR Main atmospheric gases absorbing/emitting in the IR: CO 2, H 2 O, O 3, CH 4, N 2 O, CFCs. Each atmospheric gas has a specific absorption/emission spectrum – its own signature. Continuum absorption by water vapor is defined as any observed absorption by

  • FTIR peaks: Absorbance or %Transmittance?

    However, for me the proof of whether quantitative IR "works" rests entirely on whether an accurate, precise and stable calibration model can be produced and validated against independent measurements.
