Libraries of pre-computed ATR-FTIR mixture spectra and conventional ATR-FTIR polymer spectra were used to rapidly identify three major components from an ATR-FTIR spectrum of a sample labeled “EVA”.

Characterizing Raman spectra of modified celluloses in pharmaceuticals, food, and materials industries. Raman spectra are compared and analyzed to determine spectroscopic features that can be useful in determination of physical and chemical properties.

Excitation-emission spectroscopy provides information of multiple sites in luminescent materials. As a wavelength selective technique, however, it may lead to prolonged acquisition times when high resolution is required. In this application note we demonstrate how this can be done faster, whilst maintaining high resolution.

Single reaction chamber (SRC) technology enables the digestion of up to 22 different inorganic sample types simultaneously at temperatures as high as 300oC, greatly expanding the capability of a broad range of difficult materials.
