FTIR spectrometers (Fourier transform infrared spectrometers) are analytical devices for the identification and characterisation of organic and inorganic materials at the molecular level. The absorption patterns emitted by the spectrometer are specific to functional groups and molecular structural elements. Analysing these patterns allows conclusions to be drawn about the chemical composition and structure of a substance.
The FTIR spectrometer Tensor II from Bruker is a versatile device for analysing the composition of solids, liquids and gases. Due to the high information content obtained from the analysis, a very specific characterisation of materials is possible, which means that the spectrometer can be used in a variety of application-oriented and research-related questions. These include, in particular, the identification of unknown materials, the differentiation between similar substances and the verification of the identity of known substances. The analysis is based on measuring the absorption of infrared radiation by the sample surface. Molecular vibrations are excited if a time-varying dipole moment is present. The position and intensity of the resulting absorption bands provide information about functional groups and molecular structural elements. A sample quantity of 0.5 to 1 gram is already sufficient for an analysis, whereby the radiation reaches a penetration depth of a few micrometres. It should be noted that the qualitative evaluation of the spectra allows a statement to be made about the substance class, but does not provide any direct information about the molecular formula of the analysed substance.
Typical fields of application for the Tensor II are in quality assurance, for example in the analysis of additives and additives in organic and inorganic binder systems, in the detection of impurities and contamination, polymer system analysis, decomposition and ageing analyses, defect and damage analyses and tissue analysis. The device therefore offers a broad basis for a wide range of industrial, production-related and scientific applications.
