FTIR spectroscopy offers a multitude of possible applications when it comes to the analysis of polymers like natural or synthetic-rubber. Besides incoming goods inspection and product quality control, it also allows the analysis of competitive products. With the aid of extensive spectral libraries and powerful functions for the spectra search and mixture analysis, all kinds of different materials can be quickly identified. With FTIR microscopy, it is possible to detect and analyse the smallest defects and inclusions. Furthermore, automated grid measurements allow creating chemical images that show the distribution of different sample components and contaminations.
FTIR spectroscopy is also a versatile and non-destructive method for the identification of O-ring materials. A spectrum can be measured within seconds applying the Attenuated-Total-Reflection (ATR) technique where the sample just has to be pressed onto the ATR-crystal that serves as sample interface. The ALPHA FTIR spectrometer in combination with the Eco Germanium ATR unit is the ideal tool for the identification of O-rings. The evaluation of the spectra is performed automatically by means of the dedicated Bruker O-ring library. This library contains 280 spectra of O-rings made from various common rubber materials.
