Elemental analysis of rubber samples is rather difficult, but XRF spectrometry offers some advantages relative to other more popular chemical instrumental techniques due to relatively simple sample preparation. For the excitation annular radionuclide photon sources of 55Fe and 109Cd were used. The analyses of metal content in samples of natural latex have been performed in order to investigate the relation between the low specific resistivity of the latex and the respective metal content. The results are presented and discussed.

ABSTRACT: This annual review of X-ray fluorescence covers developments over the period 2000–2001 in instrumentation and detectors, matrix correction and spectrum analysis software, 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, 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.

ABSTRACT: A study was made on the determination of elemental composition of the bread improver using energy-dispersive X-ray fluorescence. Enrichment of I and Ca was seen in the bread improver. Concentration of I with an annular 241Am radioactive source and concentration of Ca with an annular 55Fe radioactive source were determined by using standard addition method in 2π geometry. A Si(Li) detector and a multichannel analyzer were used to measure I and Ca concentrations in the bread improver.
