LaserCEM
Multi-gas monitoring system
The LaserCEM® is a turnkey multi-gas stack emissions monitor for environmental compliance, using two patented technologies: OFCEAS® (Optical Feedback Cavity Enhanced Absorption Spectroscopy) and LPS® (Low Pressure Sampling).
The combination of OFCEAS® and LPS® technologies enables high spectral analysis that is interference-free, fast, and highly accurate, whatever the gas matrix to be analyzed. Its Low Pressure Sampling makes the LaserCEM® adapted to a wide range of applications without the need to heat or dry the sample prior to analysis, considerably reducing the risk of pollutants interferences or losses, as well as installation, operating and maintenance costs.
US-EPA capable, QAL1 certified and fully pre-calibrated, the LaserCEM® continuous multigas analyzer is the perfect choice for CEMS applications.
Technology: Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) and Low Pressure Sampling (LPS)
Features
- The LaserCEM® can measure a wide choice of parameters with an unforeseen quality of measurement in terms of accuracy and resolution: HF, HCl, NH3, CH4, SO2, CO, CO2, NO, NO2, O2, N2O, H2S, CHOH, H2O…
- Double QAL1 certification (by TÜV and MCERTS) according to EN 15267 and EN 14181; incorporates the QAL3 functionalities defined by EN 14181
- Lowest certified measuring ranges for hydrogen fluoride (HF), for nitrogen monoxide (NO), and for carbon monoxide (CO)
- Direct measurement without modifying the sample
- Measurement of interferents or normalization gases (water, oxygen) with the same analyzer
- Low energy, calibration gases and compressed air consumption
- Utilizes low-pressure sampling and traced lines to prevent condensation and eliminate washout effect
- Communication, control and maintenance via Modbus, (TCP/IP, RS), analog, USB and Ethernet

Benefits
- Comprehensive stack emissions management:
LaserCEM® continuous emission monitoring system combines regulatory compliance, low cost of ownership, low maintenance, high availability, and environmental responsibility to provide a comprehensive approach to your stack emissions management. - True direct extractive CEMS:
No sample pre-treatment. OFCEAS technology associated with low pressure sampling enables direct measurement and eliminates the risk of chemical adsorption, desorption, and condensation along the sampling line. Accurate measurement even in high water contents (>80%). - Low cost of ownership:
Dust filters’ replacement drastically reduced; low use of compressed air and calibration gases; very low energy consumption (80 °C temperature maintained traced sampling line compared to 180 °C required by other monitoring systems). - Easy to use, easy to report emissions:
LaserCEM® is able to analyze all kind of gases and concentration ranges. In combination with DURAG DATA SYSTEMS' emission DAHS, the D-EMS 2020, tracking ELVs and sharing emissions reports with your local authority is amazingly simple. - Evolutive, futureproofed:
Modular system, allowing for the add of new gas parameters or new ranges: you to stay fit and compliant with future regulations or stack emissions monitoring objectives.
