Journal Article
Lee, C. J., Scurr, D. J., Jiang, L., Kenton, A., Beebe, S. R. T., & Sharp, J. S. (2021). Imaging mass spectrometry of fingermarks on brass bullet casings using sample rotation. Analyst, 146(24), 7563-7572. https://doi.org/10.1039/d1an01768c

A rotation stage was developed to allow the surface of bullet casings to be imaged under ultra-high vacuum (UHV) conditions using time-of-flight secondary ion mass spectrometry (ToF-SIMS). Experiments were performed over a period of seven months to d... Read More about Imaging mass spectrometry of fingermarks on brass bullet casings using sample rotation.

A new particle mounting method for surface analysis (2021)
Journal Article
Dundas, A. A., Kern, S., Cuzzucoli Crucitti, V., Scurr, D. J., Wildman, R., Irvine, D. J., & Alexander, M. R. (2022). A new particle mounting method for surface analysis. Surface and Interface Analysis, 54(4), 374-380. https://doi.org/10.1002/sia.7010

The chemical analysis of microparticles is challenging due to the need to mount the particles on a substrate for analysis; double-sided adhesive tape is often used (sometimes conductive), however that is usually coated with poly (dimethyl siloxane) (...
