6.4 Applications 7 Portable and mobile XRF 8 On-line XRF 9 Applications 9.1 Sample preparation and preconcentration techniques 9.2 Geological 9.3 Environmental 9.4 Archaeological and forensic 9.5 Industrial 9.6 Clinical and biological 9.7 Thin films 9.8 Chemical state analysis and speciation 10 ReferencesThis annual review of X-ray fluorescence covers developments over the period 2002-2003 in instrumentation and detectors, matrix correction and spectrum analysis procedures, X-ray optics and microfluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications as assessed from the published literature. The review also covers a survey of applications, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. During the current review period, trends were noted in the increased use of principal component analysis in the assessment of environmental data and chemometrics in the interpretation of XRF data in general, meticulous experimentation to model the emission spectra of X-ray tubes to improve the accuracy of FP correction procedures, a slowdown in reports on the development of ultra-high resolution cryogenic ED detectors, the use of EXAFS and XANES in fluorescence, as opposed to the more traditional absorption mode, continued interest in SR sources and interesting artefact measurements performed using XRF and related instrumentation. Instrumentation General instrumentation and excitation sourcesSeveral developments in the design of commercially available X-ray spectrometers feature in the literature during this review

GGR Critical Review of Analytical Developments in 2003

“…These contributions have been solicited from authorities in each field, who have drawn upon their own expertise and incorporated additional references where appropriate. The papers are not intended to serve as separate detailed reviews on particular techniques as a number of excellent publications of this kind have been published in recent years (e.g., Potts et al 2001, Albarède et al 2004. Thus, instead of revisiting the historical context or decades of development in each analytical technique, the goal here has been to capture a snapshot of "hot topics" across a range of fields as represented in the 2003 literature.…”

Portable XRF of Archaeological Artifacts: Current Research, Potentials and Limitations

“…With regard to detection systems in XRF technology in general, several detectors have been constructed, aiming at higher energy resolution and high count rate efficiency. A review of PXRF, including gamma-and X-ray detectors, by Knoll (2000) and Potts et al (2001) presented the full chronological history of all the types of detectors since 1950 that have been used for these spectroscopic regions (see also Potts and West 2008). The authors included the latest trends in portable, thermoelectrically cooled and silicon drift X-ray detectors and the more recent high-resolution cryogenic X-ray detectors.…”

Evaluation of Liquid‐ and Solid‐Contact, Pb2+‐Selective Polymer‐Membrane Electrodes for Soil Analysis

“…AAS, ICP-MS and ICP-AES are laboratory-based methods that offer reliable and sensitive results after digestion and extraction of metals from the soil samples, whereas XRF can be used to analyze the metal content of soils in situ without the need for sample collection or digestion [1].…”
