AbstractA German company settled in the North-east has developed a modular Quantum Cascade Laser (QCL) driver system for various infrared absorption spectroscopic applications. Q-MACS is an user-friendly and compact real-time concentration measurement system for industrial, environmental and medical applications. It has been developed for analysis and monitoring of plasma processes or high sensitive trace gas analysis. The company is looking for a technical cooperation and/or licence agreements.DetailsPlasma diagnostics is used for the active control of industrial plasma reactors, examines electrode ageing processes of plasma light sources and helps to explain the plasma-assisted polymerisation of amphiphile aggregates.Diagnostics and modelling provide significant contributions to the physical penetration of the complex behaviour of low temperature plasmas in experimental arrangements and technological applications. The possibility of detecting molecules of interest, despite the presence of other gases, offers in combination with a portable and highly sensitive detection system a wide range of applications for trace gas analysis in several fields and can be employed in industrial processes. The developed diagnostics system combines the benefits of absorption spectroscopic methods in the mid infrared with the favourable properties of quantum cascade lasers. Therefore, in combination with thermoelectrically cooled infrared detectors, the developed diagnostic system is well suited for industrial applications, in particular for real-time process control. The Q-MACS technology can also be used for environmental applications like trace gas analysis, explosive detection, environmental monitoring or leak testing and medical applications in real-time medical diagnostics. The company is looking for potential partners in these fields for further development and operation of the diagnostic system. Innovative Aspects: The main advantages of this measurement system are: -Mid-infrared light sources working at room temperature -High selectivity on molecular species -High sensitivity on molecular species concentration -On-line concentration measurements in plasma chambers -Environmental monitoring by sampling using sophisticated gas handling -Scalable sensitivity range by long path optics -Modular design on optical periphery -Capable of using as an OEM product -Self-monitoring easily operated system.
