Chemistry research facilities

The department houses a wide variety of instrumentation, some of which is detailed below. For a full list of the department's capabilities, please contact the senior technician for details.

Gas and Liquid Chromatography

The school has various chromatographic capabilities, including numerous GC and HPLC instruments. The HPLC instruments are equipped with UV and diode array detection and we also have facilities for Gel-Permeation Chromatography for the determination of the molecular weights of polymers. Flash chromatography systems afford the ability to separate complex mixtures of organic compounds and to isolate them in preparative quantities

Mass Spectrometry

The department has modern facilities for the measurement of mass spectra. Our suite of mass spectrometers include quadrupole, ion trap, triple quad with assorted ionisation modes including Electron and Electrospray ionization. When linked to powerful separation techniques such as Gas and Liquid chromatography these instruments provide a powerful tool for the identification and quantitation of a wide range of organic compounds. Advanced software allows library searching and deconvolution of spectra.

Nuclear Magnetic Resonance spectroscopy (NMR)

We have NMR spectroscopic facilities at both 400MHz and 500MHz. Both these instruments have automated facility and have multinuclear probes (up to silver). Both machines also have broadband solid state and variable temperature solid state capabilities (originally developed in Bangor). They are able to produce multidimensional spectra and have inverse detection capability. Both machines can do variable temperature analysis of samples. Contact our senior technician Nicholas Welsby for more details.

Infrared and Ultraviolet Spectrometry

We have a number of standard FTIR spectrophotometers for the measurement of routine samples.  UV spectra can be measured using standard instrumentation. There are facilities for kinetics measurements.

X-ray powder diffraction

X-ray powder diffraction analysis yields important information determining the atomic and molecular structure of crystals.

Atomic absorption spectroscopy (AA)

Central to the research work of the department is the ability to accurately measure the concentrations of metals. We have modern atomic absorption instrumentation and also access to inductively coupled plasma (ICP) spectroscopy – a powerful technique which can measure a wide range of elements simultaneously.

Ion Chromatography (IC)

The identification and quantitation of charged ionic species in a liquid is achieved by a modern ion chromatography system with the ability to analyse both cations and anions with conductivity detection
