Multigas Laser Analyzer

Multigas Laser Analyzers for Real-Time Measuring.

The system is based on a high-performance, tunable diode laser (TDL) gas analyzer platform. The Airoptic lasers are offered as open-path, in-situ and extractive analyzers. All variations are available as multilaser and multigas versions. A fiber optic-based version to be used under difficult conditions is also available.

The analyzers of the GasEye series provide limits of detection and measuring accuracies that outperform today's state of the art and thus set new standards in analytical technology. They can be used for measuring high-purity gases (ppb range) up to the measurement under difficult process conditions (e.g. steel industry, etc.).

Special emphasis is placed on the semi-automatic mode of the system. As soon as there is low transmission or if other negative events impair the measurement, the system switches to a safe mode in which the laser frequency is controlled by using reference data of the basic calibration. A warning is triggered allowing further temporary operation. Therefore, the user can be supported by a service technician or by remote maintenance without any problems.

Below please find a selection of possible gases that can be measured:
O2, H2O, CO, CO2, CH2O, HCHO, SO2, H2S, C2H5OH, NH3, HCI, HF, SO2, CH2, CH4, HCN, NO, NO2, N2O, …

A further highlight is the measurement of hydrogen (H2) in the process. The offered gas components can be combined as real multigas systems (real-time measurement). The possible combinations are versatile (e.g. CO+CH4, CO+CO2, CO+O2, NO+NO2, SO2+NO, SO2+HCI+NO) and can be applied in line with customer requirements and specifications. The high-performance analyzer uses the so-called Interband Cascade Laser (ICL) in the mid-infrared range and is the first "real" multigas laser on the market. The laser measuring systems are also free from cross-sensitivities and can thus be used for a wide range of applications.

The lasers of the GasEye series are characterized by fast response times (50 ms), a high sensitivity and high selectivity in the measurement. The short measuring times in the millisecond range allow optimal process monitoring and swift intervention.  Airoptic’s laser measuring devices achieve optimal measurement results even in processes with a high level of dust (50 g/m3).

No additional sample gas conditioning is required for operating the GasEye laser system (in-situ) and time delays during measurement due to sample transport (for example of highly reactive gases) are thus avoided. The laser measuring systems are calibrated once in the factory and do not require any further field calibration. 24/7 operation is thereby not endangered. The operating costs are very low and justify the slightly higher investment costs compared to conventional analytical technology in many cases.

With Airoptic’s technical expertise and M&C’s application know-how, we always provide you with the optimal solution for your application. Please feel free to contact us.
