Identifying solids and liquids for you#
How do chemical compounds change under external influences? What is the chemical composition of certain solutions or liquids? Are chemical traces left on a surface? The Fraunhofer Institute for Applied Solid State Physics IAF provides answers to these questions: Our infrared spectroscopy detects and quantifies even small traces of substances or chemical reactions, based on their molecular composition.
In our application laboratory, we offer spectroscopic measurements with our fast tunable quantum cascade lasers (QCLs). This innovative technology is based on wavelengths in the mid- to long-wave infrared range and identifies chemical substances far more reliably than comparable spectroscopic measurement techniques in the near infrared wavelength range. It facilitates clear identification of various solids and liquids within a few seconds only – culminating in real-time measurements.
Continuous on- and inline process analysis in real-time offers an enormous potential gain in efficiency as well as cost savings for the development and optimization of production processes, e. g. in the chemical or pharmaceutical industry. The influence of parameters such as temperature and pressure can directly be monitored and optimized for enhanced yield and reduced production time. It is thus possible to develop e. g. new pharmaceutical products faster and at lower costs. The QCL has established itself as an ideal laser light source for innovative infrared spectroscopy techniques in the past years. Thanks to its broad spectral tunability in the infrared wavelength range between 4 μm and 11 μm, as well as its high spectral brilliance, the QCL is ideally suited for a wide range of measurement tasks.
