Imaging mass spectrometry of fingermarks on brass bullet casings using sample rotation
(2021)
Journal Article
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.
