The synchrotron radiation microprobe at the SRS, daresbury (UK) and its applications

The use of (micro)-X-ray absorption spectroscopy in cement research

“…In view of the importance of small-scale mechanisms and molecular-level processes in complex heterogeneous systems, there has been a considerable effort to develop high resolution analytical synchrotron-based X-ray probes with which the wealth of structural information provided by XAS can be obtained on a micro-scale (Rivers et al, 1988;Vanlangevelde et al, 1990;Devoti et al, 1991;Suzuki and Uchida, 1992;Janssens et al, 1993;Chevallier et al, 1996;Hayakawa et al, 1998;Newville et al, 1999;Bohic et al, 2001;Somogyi et al, 2001;Janousch et al, 2004;Marcus et al, 2004;Scheidegger et al, 2005). For reviews on micro-probe beamlines and applications of micro-spectroscopy, the reader is referred to Bertsch and Hunter (2001), Manceau et al (2002) and Sutton et al (2002).…”

Trace element determinations using a 15-keV synchrotron x-ray microprobe

“…Applications. The synchrotron microprobe has been employed for experiments on human hair and hair roots (4), hamster tooth germs (35,36), gel electrophoresis samples, and rat brain sections. Also other types of samples have been irradiated for producing elemental distributions such as archeological bones, fluid inclusions in quartz, fly ash particles, glass particles, cosmic dust, chondrites, and other geological samples.…”

Applications of Synchrotron-Based X-ray Microprobes

“…In this discussion, we will briefly introduce the primary strategies and optics used in X-ray microprobes at synchrotron facilities. We direct interested readers to comprehensive treatments of the design, development, and application of focusing devices for X-ray microprobes and microscopes at synchrotron facilities worldwide. ,,,− ,,− …”

“…A schematic of the dedicated hard X-ray microprobe bending magnet beamline, X-26A at the NSLS, is depicted in Figure and can serve as a generic example of a hard X-ray microprobe. Similarly configured hard X-ray microprobes are operating at second- and third-generation synchrotron facilities worldwide. ,,,,,,− ,,,,,,,,,− Hard X-ray microprobes utilizing white light (continuum) provide the ability to conduct rapid nondestructive trace element microanalysis on a wide range of samples with little sample preparation. Detection limits for elements Z > 20 by SXRF at many second-generation synchrotron sources is in the low μg g -1 to high ng g -1 range with a factor of 10 improvement being realized at third-generation sources.…”
