Different Methods of analysis are available to monitor CO in ambient air like IR Absorption, IR Absorption GFC, Open path spectrometry. This presentation explains the NDIR Gas Filter correlation technique using EC9830 GFC CO Analyzer. The EC9830 analyzer operates by measuring CO absorption of IR radiation at highly specific wavelengths near 4.7 microns.
This presentation explains the UV absorption method used for monitoring ozone in the ambient air. Ozone is continuously measured by ultraviolet absorption photometry. In the…
