AbstractMicro and trace element analysis by X-ray fluorescence was carried out using synchrotron radiation from a bending magnet and an undulator for hard and soft X-ray excitation respectively. The minimum detection limits obtained in the hard X-ray region were less than pg, which corresponds to a spatial resolution of less than a hundred micronmeters, with a detection limit of a few ppm. Light elements such as oxygen, nitrogen and carbon in silicon compounds were analyzed by soft X-ray emission spectroscopy using undulator radiation. The minimum detectable amount of the light elements was greatly improved, since undulator radiation is very strong in intensity, and is highly collimated.

AbstractTotal Reflection X-Ray Fluorescence Analysis (TXRF) has become a powerful analytical tool for trace element analysis. Because of its advantages in excitation and background reduction TXRF has been applied for the analysis of light elements (C,O,F,Na,...). A special Ge(HP) detector offering an ultra thin window in combination with a spectrometer specially designed for the requirements of light element analysis was used. Also a new windowless X-ray tube for efficient excitation of the light elements was tested. The system was checked with standard aqueous solutions; detection limits in the ng range (7 ng for O) are obtained.

AbstractTodays demand for rapid trace element analysis in pollution control and resource materials has led to the development of a completely automatic, very sensitive and stable Si(Li) X-ray analyzer. The key element, a transmission target tube, which has inherently a very clean monochromatic X-ray output, has been studied in view of efficiency, sensitivity and stability. The transmission target tube requires different operating criteria than conventional X-ray tubes. An analysis was made to “explain” these differences using fundamental X-ray physics. Studies included various experiments directly applied to practical problems in analysis of pollutants and mineral resource materials.

AbstractX-ray fluorescence induced by charged particles has been employed in trace element analysis of both animal and human blood, tissue and bone samples. Preparation techniques included microtome slicing and wet digestion in nitric acid, internal chemical standards being used in the latter case.Most of the specimens arose from a study of interactions between the toxic elements lead and zinc in growing foals; this was motivated by reports of sickness and death in foals raised near lead-zinc smelters. The cause of toxicity in animals from environmental pollution is often attributed to Single factors, whereas in reality interactions among many factors, including a variety of toxic and nutrient trace elements, should be considered.A variety of spectra are presented and elemental concentrations derived. Agreement between the X-ray data and atomic absorption spectrophotometry is encouraging. The results demonstrate the potential of particle-excited X-ray fluorescenee as a broad-range analytical technique for the study of trace element interactions.

The ability rapidly and quantitatively to detect trace elements in a host matrix is of great importance in many areas of science and engineering. This fact is underlined by the considerable amount of effort that has been put into developing such techniques as electron probe microanalysis, proton Induced x-ray emission (Pixe), the laser microprobe mass analyser (Lamma) as well as conventional x-ray fluorescence methods. Recently the availability of electron storage rings partially or wholly dedicated to producing intense beams of synchrotron radiation has provided a new tpol to complement the above mentioned techniques. This paper reports on work at Daresbury Laboratory on synchrotron x-ray fluorescence (SXRF) fo r quantitative trace element analysis.

An X-ray microprobe system for X-ray fluorescence (XRF) analysis and spectroscopy has been developed at SPring-8 BL39XU; it comprises an X-ray focusing or collimation system, energy-dispersive (ED) and wavelength-dispersive (WD) XRF spectrometers, and a sample-scanning system. The conventional ED spectrometer will be utilized for qualitative and quantitative trace-element analysis, and the WD spectrometer will be used both for trace-element analysis and XRF spectroscopy. A combination of monochromated undulator radiation and the WD spectrometer will enable resonant XRF spectroscopy using brilliant hard X-ray undulator radiation.
