What are CEM’s and why is it needed?
A continuous emission monitoring system (CEM’s) is the analytical equipment necessary for the determination of a gas concentration or emission rate of pollutants.
Around the world, CEM’s are required under local regulations for either continual compliance determinations or determination of exceedances of the standards (EN 15267 in EU, EPA in USA, etc.). Industrials use CEM’s gas analyzers to prove their compliance to emission regulations to environmental control authorities.
These online gas analyzers are used in industries with sensitive exhaust such as power plants, cementeries, refineries, incinerators, boilers, etc.
The LaserCEM® uses the patented OFCEAS technology, based on extractive absorption spectroscopy. This laser based technology is able to measure gases from percentage to ppb concentration ranges, with an unforeseen quality of measurement in terms of accuracy and resolution.
The LaserCEM® samples the gas at low pressure. This dilution reduces the particles content and the dew point in the sampling line.
With LaserCEM® filters replacement is drastically reduced and heating of 180°c is avoided. Finally, LaserCEM® has an integrated auto calibration of the measurement system, preventing from drift under normal use of the instrument.
Therefore LaserCEM® is able to analyze all kind of gases and concentration ranges, with limited services and maintenance costs.
is a complete pre-calibrated multi-component (NO, SO2, CO, HCl, CO2, NH3, H20, 02, C02, NO2, HF) laser infrared spectrometer for CEM’s analysis.
