What is CEMS Analytical Technology?
CEMS analytical techniques are based on the measurement of both physical and chemical properties of the parameters of interest. Selection, however, may be limited by the source or stack conditions or otherwise dictated by the approval requirements.
Commonly used online analytical techniques for gases include absorption spectroscopy, chemiluminescence, mass spectroscopy, UV fluorescence, paramagnetism, etc. Stack gas flow is normally measured using pressure differential, thermal, or ultrasonic techniques.
