NERC Ion Micro-Probe Facility (SIMS)

The Facility carries out in-house research and provides a service to the earth and environmental science community. It is funded by the Natural Environment Research Council (NERC). The Ion Micro-Probe (Secondary Ion Mass Spectrometry, SIMS) Facility is located in the School of GeoSciences, Grant Institute at the University of Edinburgh.

Instrumentation

Cameca ims-4f

The Ion Micro-Probe Facility is equipped with a Cameca ims 4f and a Cameca 1270 and is supported by NERC under its National Capability portfolio.

The Cameca ims 4f was installed in September 1988 and despite its age it still is the instrument of choice for multiple element analysis, and is ideal for the analysis of H in nominally anhydrous minerals. Equipped with a He cryo-pump, Liquid Nitrogen cold trap and a sample air lock than can hold, pre-pump and bake eight samples prior to analysis, it is perfect for light element and volatile analysis (e.g. H, Li, B, C, F etc).

The Cameca 1270 was installed in January 2003 and provides better sensitivity and higher precision than the Cameca ims 4f. Dramatic improvements in external repeatability of isotopic ratio measurements for stable isotopes (O, Si, C, S, Li, B...) have been achieved, while the high transmisson of the 1270 at high mass resolution has enabled new areas of geochronology (U/Pb, Th/Pb, Th/U in Zircon, Monazite and Allenite) to be developed.

 

 

What's New and News.

Cameca 7f-Geo
The 7f-Geo is starting to take shape (April 2018)

1) Cameca ims 7f-Geo: An order has been placed with Cameca for a ims 7f-Geo fitted with the Hyperion RF ion source. The instrument will be installed in October 2018 and be available as part of NERC's Service and Facilities National Capability in April 2019. (Image courtesy of Joel Bonnet, Cameca)

The IMS 7f-GEO is equipped with a new, unique detection system combining a double Faraday cup detector system and an Electron Multiplier. Thanks to this configuration, acquisition time is shortened, and analyses are run in a pseudo bi-collection mode ensuring sub-permil precision for stable isotope ratio measurements. The double Faraday cup system is combined with a fast mass peak switching system (as fast as 0.3 sec at high mass resolving power) for further benefits in terms of precision and analysis throughput.
