“…In addition to providing information about the bulk composition of a material, analysts are increasingly asked for speciation of elements present. To satisfy such demands Geyer et al 9 optimised a cold cathode tube as an excitation source for soft X-ray spectrometry. Different cathode materials (aluminium, titanium and steel) were investigated with the titanium option offering a stable discharge over a long period of time, making it suitable for practical work.…”

“…The authors reported that the lateral distribution and the physical status of the contaminants could seriously affect the results. The correlation between TXRF spectrometry and surface SIMS was investigated by Smith et al 145 Results for Fe were found to be in good agreement for concentrations in the range 8610 9 to 2610 15 atoms cm 22 but differences were found for W and Cu when the contamination was not uniform across the surface or extended to a significant depth below the surface.…”

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, publications have demonstrated the development of sub-100 nm X-ray beams for SR microprobe analysis together with the wider use of WD spectrometers in this application. There is evidence of an extension of the application of XRF as a reference technique, with XRF increasingly being used in modern laboratories in place of older wet-chemical methods, and computer-modelling studies continue to be popular in extending the understanding of various XRF phenomena. Some interesting work has been undertaken in the measurement of radiative Auger effects using high-resolution WDXRF instruments. However, the potential for future developments in XRF is illustrated by research into ultra-high resolution microcalorimeter detector devices, which are still at the experimental stage and have not yet progressed to the status of useful practical devices.
