A variety of analytical and spectroscopic instruments are housed within the University of Bath Imaging Facility.

Fourier Transform Infrared Spectroscopy (FTIR)

A Perkin Elmer Frontier FTIR spectrometer is equipped with the following: diamond ATR head, DRIFT attachment for powders, gas cell, transmission cell and an improved resolution MCT detector. It is a bench top instrument used to analyse samples such as hydrocarbons, oils and pharmaceuticals. It can also be used for the determination of surface functional groups.

Raman Spectroscopy

Raman spectroscopy is carried out on an inVia confocal Raman microscope with a full spectrum of laser sources:

  • Red (785 nm) 140 mW,
  • Green (532 nm) 69 mW,
  • UV (325 nm) 6.5 mW.

The chemical composition and the molecular structure of a sample may be determined, or stress measurements and phase imaging performed. This is a high throughput, non-destructive technique, and although lower in imaging resolution than an electron microscope, offers a more dynamic method for investigating chemical properties of materials ranging from biological cells to semiconductor devices.
