LaserCEM®

In response to environmental challenges and given ongoing technological development, many industries are confronted with more and more stringent regulations governing emission limit values. This is where the LaserCEM® from AP2E, a 20 year specialist in industrial gas analysis systems and member of DURAG GROUP, comes into play. The LaserCEM® is a laser-based analyzer using the patented OFCEAS® (optical feedback cavity enhanced absorption spectroscopy) to improve upon standard TDLAS and other laser-based technologies performances. It is an industry technological breakthrough. It offers a more accurate, efficient and sustainable solutions for continuous monitoring of gaseous pollutant emissions.

YOUR SOLUTION TO REGULATORY

AND ENVIRONMENTAL CHALLENGES

Air quality and the monitoring of industrial emissions play a major role in public health. Industrial stacks, for example, are subject to new regulations requiring continuous monitoring of pollutants at ever lower concentrations. The problem: conventional technologies for this type of measurement (NDIR, FTIR, etc. - even traditional TDLAS and other laser-based analyzer solutions) are reaching their detection limits for many pollutants. This is exactly where LaserCEM® comes into play. 

The LaserCEM® utilizes patented OFCEAS® technology, a high-resolution absorption spectroscopy technique engineered to improve on existing laser-based spectrometer solutions. As a multi-gas analysis system, this laser-based technology enables unrivaled measurement quality in terms of accuracy and resolution, allowing measurement of gases in concentration ranges from percent to ppb.

OFCEAS® TECHNOLOGY: UNRIVALED ACCURACY, MINIMIZED MAINTENANCE + LOW OWNERSHIP COSTS

LaserCEM® operates with LPS® (low-pressure gas sampling) and a heat-traced sampling line, only maintained at maximum 80 °C in order to avoid condensation and guarantee accurate, consistent measurements. In addition, this technology reduces total sample mass flow, and therefore the amount of impurities. As a result, maintenance is minimized and sample transfer at 180 °C is avoided, considerably reducing the energy consumption of the analysis system. The very short response time and low sample volume required by the use of LPS®technology enable longer sample line lengths than conventional heated lines, and therefore greater ease of installation of the analysis system at lower cost. 

The combination of OFCEAS® and LPS® technologies enables fast, highly precise and interference-free spectral analysis, whatever the gas matrix to be analyzed. Thanks to its LPS®, LaserCEM® can be adapted to a wide range of applications without the need to heat or dry the sample prior to analysis, which greatly reduces installation, operating and maintenance costs.


KEY FEATURES



UNIQUE SELECTIVITY AND PRECISION

LaserCEM® OFCEAS® technology generates a high-resolution absorption spectrum in the picometer range, always in combination with the zero signal. This unique capability minimizes or eliminates interferences, ensuring accurate and reliable measurements of various gases. Thanks to its exceptional selectivity, the system can clearly distinguish gases in complex matrices, offering unrivaled accuracy in pollutant detection. With LPS® technology, absorption spectra are so well defined that cross-sensitivity phenomena are virtually non-existent, enabling measurement of pollutants even in matrices containing over 60% water. 

Because the system enables direct measurement without sample modification, it ensures maximum representativeness, guaranteeing measurement of peripheral parameters (water, oxygen) with the same analyzer.


DIRECT MEASUREMENT, EXCEPTIONAL SENSITIVITY

Thanks to an optical path of up to 10 km, signal intensity is multiplied by 1,000 compared with conventional technologies. This enhanced sensitivity enables the detection of extremely low concentrations of pollutants with exceptional accuracy, down to parts per billion (ppb). 

The system provides direct measurement without sample modification, with unrivaled response times ensuring maximum integrity of the data collected. It is delivered fully pre-calibrated, eliminating the need for daily zero and span calibrations.

LaserCEM® requires no nitrogen, zero air, dilution air or other carrier gases, simplifying operation and reducing operating costs.



DOUBLE QAL1 CERTIFICATION FOR 

MEASUREMENTS THAT ARE ALWAYS ACCURATE


The LaserCEM® is a turnkey multi-gas analysis system for continuous, simultaneous measurement of multiple gases such as HF, HCl, NH3, CH4, SO2, CO, CO2, NO, NO2, O2, N2O, H2S, CHOH, H2O, etc. It benefits from double QAL1 certification (by TÜV and MCERTs) in accordance with EN 15267 and EN 14181 and incorporates the QAL3 functionalities defined by EN 14181. 

Only two reference gas cylinders need to be connected to the QAL3 module. It manages the injection of standard gases at the head of the sampling system, enabling the entire measurement system to be checked. Very low reference gas consumption ensures an extended gas cylinder change interval of up to one year, reducing costs for gases and labor.



MODULARITY AND LOW ENERGY CONSUMPTION: 

ASSETS FOR A SUSTAINABLE FUTURE


LaserCEM® is designed and certified as a modular system, making different configurations and the addition of new gases or measuring ranges possible. This flexibility supports users in bringing their installations up to standard. Companies can easily adapt to new regulatory requirements with no need to invest in a completely new system, reducing costs and wasted resources.

The technology is used in marine applications, guaranteeing the availability of spare parts or upgrades for over 25 years. 

LaserCEM® also features much less energy consumption than other current analyzers. In fact, the system achieves energy savings of 50 to 80%, depending on the length of the sampling line. This energy efficiency helps to reduce the carbon footprint of emission monitoring operations, bringing industrial practices in line with sustainable development objectives.



GROWING ADOPTION BY INDUSTRY


Many industries are gradually adopting this technology. Interest is greatest in the energy production, chemical, metallurgy and waste-to-energy sectors, where pollutant emissions are particularly tightly controlled.

With its growing adoption (several hundred installations are already in service), LaserCEM® promises to become an essential tool for monitoring emissions into the atmosphere, paving the way for a cleaner, more sustainable future.
