SIMS Facility
Secondary Ion Mass Spectrometry
Secondary Ion Mass Spectrometry (SIMS) is a highly sensitive surface analytical method that can investigate the chemical character of a solid substrate. The technique uses a range of incident ion sources to impact on solid surfaces and generate secondary ions that can be analysed by either a high mass resolution Orbitrap analyser or a high imaging resolution time of flight (ToF) analyser. A single secondary ion mass spectrum can be used to describe the constituents of one point on a surface. Alternatively, if the incident beam is rastered across several points within a given surface area, it is possible to build a chemical image map of that surface. It is also possible to sputter through the top layers of inorganic or organic surfaces while monitoring the 3D profile of elemental or molecular species (i.e. depth profiling).
UoN SIMS Facility
The OrbiSIMS facility was set up with a £2.5m EPSRC Strategic Equipment Award ‘3D OrbiSIMS: Label free chemical imaging of materials, cells and tissues’ 2017-2023 (EP/P029868/1). The capability of the facility has grown from this initial investment, now including a second ToF-SIMS instrument and employing 3 members of staff to manage the facility and its userbase, undertake data acquisition, provide researcher supervision, conduct training and respond to external enquiries.
