FT-IR Nexus

• Tecnical description

  Nicolet Nexus 870. Instrument for FT-IR spectroscopy and microscopy, model Nicolet Nexus 870, equipped with external optical table, two external detectors (MCT e TRS), GeATR, one Hind photoelastic modulator, and one IR Continuum microscope. The instrument allows for the contemporaneous imaging and FT-IR analysis of micrometric particles/domains, allowing for the chemical mapping of flat samples as well as powders.

• Research areas and applications

  FTIR (Fourier transform infrared spectroscopy) is a fast, easy and reliable technique for material identification and quantification of constituents in a sample. The combination with optical microscopy allows for the chemical mapping of complex systems and interfaces, such as mixtures, surface coatings, films, pharmaceuticals, etc.
