Spectroscopic equipment

Spectroscopy is a powerful laboratory technique used to determine the structure and concentration of a sample based on the amount and wavelengths of light that it absorbs. NMR spectroscopy is a powerful tool for identification of compounds.

Our available spectroscopic equipment is listed below.

Atomic Absorption Spectroscopy (Flame)

GBC Avanta AAS with deuterium background correction. Used for analysis of ppm-level metals, ppb-level metal hydrides, and mercury by the cold-vapour method. Location: F3.15. Contact: Annie Barker.

Atomic Emission Spectroscopy

Can be carried out on the GBC Avanta AAS instrument (above). Location: F3.15. Contact: Annie Barker.

Electron Spin Resonance (ESR)

Varian E104A fitted with variable temperature device for the detection and characterisation of paramagnetic species such as free radicals and transition metal ions. Location: C3.06. Contact: Graham Saunders.

Infra-Red Spectroscopy>
