Spectroscopy

Spectroscopic methods can be used to examine solids, liquids and gases: light of a certain wavelength is reflected, scattered or emitted by a specimen. This takes place in a specific way, according to the chemical substance, thus permitting qualitative and quantitative information to be derived about the compound under investigation.

In the field of gas and process technology, Fraunhofer IPM uses a wide range of spectroscopic methods. In addition to laser spectroscopy, the expertise of the insitute also extends to many classic methods such as Fourier transform IR spectroscopy (FTIR), photometry, filter, UV and Raman spectroscopy and photoacoustics. Thanks to chemometrical evaluation methods, we gain a maximum of information from our measurement data.

 

Laser spectroscopy

We harness technical advances in laser development to open up new areas of application for sensitive gas and liquid measurement.

 

Raman spectroscopy

We leverage the specific advantages of Raman spectroscopy to characterize chemical substances and pure substance concentrations in mixed substances.

 

ATR spectroscopy

We develop ATR-based sensors for liquid analysis that provide accurate measurements even in harsh environments.

 

Photoacoustic
spectroscopy

Gases can be detected very precisely and selectively by means of photoacoustic spectroscopy (PAS). 

 

Absorption

Absorption spectra provide an optical fingerprint.
