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.

 

Absorption
spectroscopy

 

Absorption spectra provide an optical fingerprint.

 

ATR spectroscopy

 

ATR measurement technology – from the lab straight to the process

 

Raman spectroscopy

 

Raman spectroscopy allows the reliable identification and quantification of chemical substances and mixtures.

 

Photoacoustic
spectroscopy

 

We develop miniaturized PAS gas sensors – for example for indoor air monitoring.

 

Laser spectroscopy

Technical progress in the field of laser development opens up new fields of application for sensitive gas and liquid measurement.

 

Photothermal
spectroscopy

Photothermal spectroscopy permits very sensitive detection of trace gases or residual absorption.
