OVERVIEW: Liquid Phase Photoelectron Spectroscopy (LiPPS) and Associated X-ray Photoelectron Spectroscopy (XPS) Facility. The principle aim of this ITT activity is the establishment of a new University of Nottingham facility for the provision of an XPS analysis for both solid and liquid based research samples and will provide significant expertise and flexibility in the measurement of liquids and soft materials. To ensure maximum instrumental access and indeed the quality of instrumentation and data, we seek to arrange a high level of on going servicing/support to achieve maximum sample throughput and experimental impact. New XPS instrumentation (Requirement 1) is required to support research activities that span the Faculties of Science and Engineering in addition to the re-location of existing instrumentation (Requirement 2). Some of our critical and primary performance requirements include a reliable X-ray source that is proven to deliver a high flux of incident photons of energies within the range 2.5 to 4.0 KeV. The X-ray source MUST be monochromatic and have an operational the line width less than 2.5 eV, there is a working preference to Ag L infinity (2984.2 eV). The ability to switch monochromated X-ray sources from Hard (Ag L infinity to Soft (Al K infinity), with minimal instrument reconfiguration and loss of experimental time is also a requirement. The existing XPS is currently provided by a Kratos Axis Ultra instrument (ULTRA-1) which as part of this ITT is required to be re-located into the new XPS facility. Currently this instrument runs all samples both solid state and liquid. As a result of this tender process the ULTRA-1 instrument will predominantly investigate solid samples. The new equipment to be purchased is to be dedicated primarily to the investigation of ionic liquid samples (LiPPS). The instrument will be co-located in the new XPS facility. Liquid-based samples are typically composed of ionic liquids or solutions thereof, the vapour pressures of which are vanishingly small, rending then suitable for study under UHV. (NB - there is no expectation to include ambient pressure XPS of materials not compatible to UHV). The new LiPPS instrument is designed to probe solution processes, e.g. chemistry, by moving to a harder X-ray source (i.e Ag L infinity) which is more bulk sensitive in the normal emission mode, of course, increased surface sensitivity may be obtained by moving to a grazing angle, i.e. angle resolved XPS (AR-XPS). LiPPS is complimentary to traditional XPS analysis, using softer sources, and as such will support the national XPS facility (NEXUS), located in Newcastle. Full data compliance across systems both at UoN and indeed NEXUS is essential. Servicing of the new LiPPS instrument (Requirement 1) for 3 yrs must be included and on the relocated ULTRA-1 instrument (Requirement 2) for a minimum of one year, full warranty is required on both instruments. Additional provision for maintenance cover of LiPPS and ULTRA-1 instrumentation is required, taking the form of either i) extended warranty or ii) pre-purchase of engineering support (or parts) at preferential reduced rates. This Tender is set out with 2 main requirements, bidders may tender for either requirement or both.
