Product catalog summary

Introduction to CEM's:
A Continuous Emission Monitoring System (CEM's) is essential for determining gas concentrations or emission rates of pollutants. These systems are mandated by local regulations globally to ensure compliance with emission standards, such as EN 15267 in the EU and EPA in the USA. Industries like power plants, refineries, and incinerators use CEM's to demonstrate regulatory compliance to environmental authorities.

LaserCEM® Technology:
The LaserCEM® employs patented OFCEAS technology, utilizing extractive absorption spectroscopy. This laser-based technology measures gas concentrations from percentage to parts per billion (ppb) with high accuracy and resolution. The system samples gas at low pressure, reducing particle content and dew point, which minimizes filter replacements and avoids heating to 180°C. It features integrated auto-calibration, preventing drift and reducing maintenance costs.

Key Features of LaserCEM®:

Highly sensitive with low detection levels (ppb).
Highly selective with a traced line at 40°C.
Complete pre-calibrated laser infrared spectrometer.
No zero or span drift, eliminating the need for daily calibration.
No requirement for nitrogen, zero air, purge, or other carrier gases.
Capable of measuring from ppb to percentage levels.
Multigas analyzer for NO, SO2, CO, HCl, CO2, NH3, H2O, O2, CO2, NO2, HF.

continuous emission monitoring - CEM - application note-3

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...
