My current role at the UoS - Electrochemistry Research Group, is to provide specialist technical support and manage the state-of-the-art Chemical Nanoanalysis Scanning Electron Microscope facility (CNSEM). I can consult, assist and perform data collection and materials characterisation in research projects, collaborations and commercial work. The CNSEM facility was awarded by EPSRC and installed in early 2022. It offers a high resolution field emission scanning electron microscope (FE-SEM), in combination with dual energy dispersive spectrometers (EDS) and correlative Raman spectrometer. These are supplied by Carl Zeiss, Oxford Instruments and WITec respectively. The first EDS detector is suitable for elemental composition analysis, typically between 5 – 30 kV at high throughput mapping. While the second EDS is windowless with element detection down to Li Ka (56 eV) and intended for low energy work <5 keV for superior surface sensitivity. For the Raman analysis the sample is translated over to a 100x objective lens within the chamber, where the laser spot size is ~432 nm, offering sub-micron mapping capability. Raman offers complimentary chemical information to EDS, allowing you to fingerprint polymers, ordered and disordered structures.
