FTIR - Fourier transform infrared spectroscopy

A wide spectrum of everything from liquid samples to powder samples to solid, among others, can bested tested in accordance with DIN 51451 using Fourier transform infrared spectroscopy (FT-IR). Practically any material that is active in the infrared range of the light spectrum can be measured. We are able to handle just about any measuring task by using liquid cell, ATR reflectance or IR microscopy methods. FTIR spectroscopy also include comprehensive sample preparation, for example, the creation of KBr tablets or the separation of a layer of paint from a metal sheet.

Eluates from component surfaces can also be analysed and assigned by using IR microscopy.
To do this, component sections are washed with highly efficient solvents and the eluate is evaporated on a KBr substrate. This method plays a major role in residual contamination analysis or if it involves inadequate paint adhesion.

ATR spectroscopy permits the measurement of opaque layers by means of reflectance. This method is often used for the identification of polymers.
