The fourier transform infrared spectroscopy (FTIR) lab is equipped with a Nicolet Nexus 670 FTIR spectrometer with an IR PLAN microscope attachment. The microscope (with MCT detector) allows an analysis size (or resolution) as small as 30 microns in transmitted or reflected mode.

The main bench also has a sample compartment often used for powdered samples pressed into KBr pellets (DTGS detector). In the Mid-IR region (400-4000 cm-1) a Glowbar source and KBr beamsplitter are used, whilst for Near-IR (4000-7500 cm-1) a halogen white light and CaF2 beamsplitter are available.

This facility is mainly used to study and measure water and CO2 incorporated into glasses and minerals.
