These offer some decisive advantages over the formerly used dispersive spectrometers. For example, the measurement times are relatively short and the signals obtained are strong.<\/p>\n<h4>Types of Sample Preparation and Analysis<\/h4>\n<p>Since most elastomers are black and therefore not translucent nor permeable to infrared light, this requires special sample preparation techniques. Pyrolysis FTIR analyses the condensed vapour of a thermally decomposed elastomer sample, which is transparent to infrared light.<\/p>\n<p>Attenuated total reflectance (ATR) is a sampling method in which light is shone on a sample to obtain information about its structure and composition. It enables the analysis of solid and liquid material samples.<\/p>\n<p>Also extracts of elastomers are analysed. Hot extraction separates many components of the formulation from the rubber, making them easier to dissolve and to identify using IR spectroscopy.<\/p>\n<h4>Significance of IR Spectroscopy for Application Technology<\/h4>\n<p>FTIR analysis is a frequently used analytical method in elastomer technology. Within the framework of quality assurance, it allows polymers to be determined quickly and easily with a manageable amount of effort. After all, every formulation has a typical ATR band spectrum (medium resolution) as well as a typical spectrum of the extracts (high resolution). These are used to prove the sampling status of a formula with regard to the substances it contains. Combined with other analytical techniques, IR spectroscopy with its special forms is a proven tool for damage analysis.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1qtfk-3-86401de83b3b9ae5718aea8601e14aa5\">\n@keyframes av_boxShadowEffect_av-1qtfk-3-86401de83b3b9ae5718aea8601e14aa5-row {\n0%   { box-shadow:  0 0 0 0 rgba(164,164,164,0.4);
