Carbon Dioxide, CO 2

Carbon Dioxide, CO 2 Fortunatly HCl is not present in high concentrations and it does not absorb very strongly. CO 2, however, is present at higher concentrations and it absorbs strongly in the IR.Because CO 2 has more than two atoms, it can vibrate several …

Gas Measurement Using FTIR, GCNS and Ion Selective ...

FTIR Spectroscopic Analysis The FTIR spectrometer was calibrated with commercial samples of HCFC-22, HCFC-124, HCFC-123, HF and HCI. Quantitative analysis of the agent and acid-gas products in the fire tests was obtained by comparing infrared absorption peaks from the fire gases with the reference peaks obtained using the calibration gases.

Introduction to Gas Phase FTIR Spectroscopy

FTIR analysis can be used to monitor the quality of individual gas samples (e.g., pure specialty gases) or to create concentration trend charts from flowing sample streams (e.g., continuous emissions monitoring—CEM). Unlike gas chromatography (GC), FTIR spectroscopy can measure rapid changes in sample concentrations to
