School of Chemistry at Bangor University
Bangor University’s School of Chemistry houses all the analytical equipment and expertise needed for R&D work. We have extensive research facilities at the School of Chemistry which are available to our commercial partners. These include:
Facilities and Analysis
- Gas Chromatography (GC) and Gas Chromatography / Mass spectrometry (GCMS)
- High Performance Liquid Chromatography (HPLC) and Liquid Chromatography / Mass spectrometry (LCMS)
- Gel permeation chromatography (GPC)
- Mass spectrometry - Direct Insertion EI and Direct Infusion ESI techniques
- Ion Chromatography (IC)
- Flash chromatography (Preparative)
- Nuclear Magnetic Resonance spectroscopy (NMR)
- Ultra violet / visible spectroscopy (UV/Vis)
- Infra-Red spectroscopy (IR)
- Atomic absorption spectroscopy (AA)
- X-Ray diffraction (XRD)
- Thermo-gravimetric analysis (TGA/DSC)
Gas and Liquid Chromatography
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.
We house modern facilities for the measurement of mass spectra. Our suite of mass spectrometers include quadrupole, ion trap, triple quad and time-of-flight instruments 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. The 500MHz machine also has the possibility of being connected to other systems such as LC and MS. Contact us directly 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 and Thermo-gravimetric analysis
Both X-ray powder diffraction and thermogravimetric analysis yield important information about the surface and bulk properties of materials and these instruments provide essential physical and chemical data for research.
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.
These are in addition to well-equipped research laboratories for physical measurements, synthetic and trace analytical work as well as a team of experts working on the Beacon+ project.
