X-ray fluorescence spectrometry

Abstract

This annual review of X-ray fluorescence covers papers published over the period 1998–1999 that are judged to have made a significant contribution to this branch of the analytical sciences. The review is both comprehensive in scope and selective in the choice of contributions included. The scope includes developments in instrumentation and detectors, matrix correction and spectrum analysis software, X-ray optics and microfluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications. Also included is a review of applications, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films and chemical state analysis, including speciation. Highlights of this year include further work in the development of high resolution detector devices based on both microcalorimeters and superconducting tunnel junction devices. However, there continue to be important developments in capillary X-ray optics, portable XRF, on-line applications, TXRF and synchrotron radiation devices. Furthermore, it is noteworthy that XRF continues to make an essential contribution in a wide range of applications where the non-destructive, high precision, simple sample preparation techniques and well-characterised spectrum interpretation and quantification procedures can be used to advantage.
