FTIR
We have a Perkin Elmer Spectrum One Fourier Transform Infrared (FTIR) spectrometer, and a Perkin Elmer Spotlight Imaging FTIR microscope. For surface analyses, we also have a Specac Golden Gate ATR accessory, with a single reflection 45° diamond IRE.
Infrared spectroscopy is a well established technique to identify functional groups in a molecule based on its vibration modes at different infrared frequencies. The analysis of samples can be performed using a flow-cell device; as liquids or solids on the top of the ATR crystal; or ground powders or freeze-dried materials mixed with an alkali halide powder and moulded onto a pellet. FTIR is part of our UKAS accredited services, and the qualitative analysis is carried out by functional group identification, or comparison of IR absorption spectra of unknown materials with those of known reference materials, or both.
