A SelFrag facility to underpin UK geoscience

The UK is at the forefront of geoscience, which includes isotope metrology, micropalaeontology and crystallography. All these techniques rely on the measurements of natural samples (rocks, soils, fossils, minerals, metals, animal matter) from which specific components can be isolated. These components have to be contaminant-free and in some cases, such as microfossil examination, diatom characterisation, and thermal history reconstruction using thermochronology the component parts need to be intact (e.g., complete apatite crystals). The SelFrag system is a laboratory scale solution for selective fragmentation of a wide variety of materials used across the NERC science remit. It is the only extraction system that can liberate such components whole without mechanical breakdown of the materials. The SelFrag uses a high voltage discharge to fragment batches of material and liberate individual components from the whole, whether rock or electronic waste. The SelFrag system is self-contained, compact, and constructed in Switzerland to meet all EU health and safety regulations. The system is ideal for use in geosciences, mining, and recycling research and establishment of this capability in the UK is long overdue. Currently numerous laboratories and investigators throughout the UK access this capability abroad on a pay-as-you-go basis - UK research funding is supporting international operations, which is both a waste of money and turnaround is slow. For researchers without funding to pay for access, this technique is inaccessible and studies have to make do with inferior samples for analysis.Currently SelFrag is not available in the UK and hence establishment of this laboratory will provide a unique analytical resource. SUERC will operate this laboratory in an open access format through the NERC National Environmental Isotope Facility, a cluster of laboratories that provide community provision in isotope geochemistry. By using this delivery model the SelFrag capability will be accessible by all UK investigators that work within the NERC remit. Under the auspices of UK Research and Innovation, the project team will also look to provide provide unique sample preparation solutions to researchers operating within the remit of STFC and EPSRC (e.g., meteorite research, electronics, recycling). Our proposed delivery model will ensure maximum impact from NERC capital investment, the kit underpinning the first steps of many scientific experiments/projects - sample preparation.Scientists and technical staff who are currently employed at SUERC will operate the SelFrag system thereby providing significant added value to NERC and the UK user community. The team that will deliver the capability are experienced in delivering community-based technical facilities and capability - the SelFrag is highly complimentary to the capability offered by NEIF. Community demand has been established through protracted discussion with PIs and the NERC Doctoral training Partnerships and the establishment of a SelFrag laboratory at SUERC has potential to benefit every academic institution within the UK and provide cutting-edge training to PhD students in the environmental sciences. It will allow for UK-based scientists to be competitive internationally with respect to preparation of minerals, rocks, metals, fossils etc. and thus remain at the forefront of their areas of research.
