AbstractThe rapid progress of x-ray fluorescence analysis spectrometers has been closely associated with advances in computers. Due to the power of computers, it is possible to acquire the data automatically and interpret complex information accurately and quickly, so as to provide both qualitative and quantitative analyses. It is now about thirty years that computers have been applied to X-Ray Fluorescence Analysis (XRFA). Few workers have discussed the style of the various approaches, although many different software packages have been used for XRFA. Requirement analysis has been performed for Energy Dispersive (ED) XRFA, and preliminary designs are given for three types of structures: i. Sequence structure, ii. Tree structure, and iii. Net structure.

AbstractThe use of energy-dispersive X-ray fluorescence analysis (XES) for the routine identification of three tephras (Mazama, Bridge River, Mount St. Helens Yn) commonly found in archeological sites in British Columbia has been investigated. Researchers have often assumed that chemical analysis of bulk samples of glass separates would be hampered by contamination and weathering effects. Our results indicate that XES of bulk glass separates provides a very reliable method for rapidly identifying the three tephras in question, even with a very simple sample preparation. This should enable persons not skilled in geology or in tephrochronology to collect and to identify samples of these tephras. Finally, as a part of the study, similar measurements were made on the separated glass portions of these three tephras and of three others (Glacier Peak B and G, White River) from northwest North America. The results suggest that this method may provide tephrochronologists with a useful additional tool for studying tephras in other regions.

Sample Chamber

A system, has been designed and tested for rapid energy dispersive diffractometry and simultaneous fluorescence analysis. A turntable composed of the sample chamber with attached air-cooled x-ray tube allows the 2θ angle to be varied with respect to the stationary Si(Li) detector. Data for most analyses can be obtained in one minute per sample. Results are stored in the memory of a multichannel analyzer and are read out on a CRT, strip chart recorder or tabulated in digital format by a computer.
