Analysis of Sagunto Ibero-Roman votive bronze statuettes by portable X-ray fluorescence

Multi-element analysis by portable total reflection X-ray fluorescence spectrometer.

Multi-element solutions containing the 11 elements S, K, Sc, V, Mn, Co, Cu, Ga, As, Br and Y were analyzed by a portable total reflection X-ray fluorescence (TXRF) spectrometer. The excitation parameters (glancing angle, operational voltage and current) and sample amount were optimized for the portable TXRF in order to realize the smallest possible detection limits for all elements. The excitat...

Field portable X-Ray fluorescence for rapid analysis Of titanium dioxide on air filters

Field portable X-Ray fluorescence for rapid analysis Of titanium dioxide on air filters. ii ACKNOWLEDGMENTS This study would not have been possible without the help from several different resources. I would like to thank Kent Candee for the access to the field portable x-ray fluorescence analyzer, which was my biggest concern from the beginning of the project. I would also like to thank Pam Kos...

Multielement analysis of soft drinks by X-ray fluorescence spectrometry.

Several commercial soft drinks and respective plastic bottles were analyzed for their multielement contents employing the synchrotron radiation total reflection X-ray fluorescence spectrometry technique (SRTXRF). The SRTXRF method has been developed and validated, and about 20 elements were detected in the investigated samples, including some trace elements, which can be toxic for human beings,...

Analysis of Tclp Extracts by X-ray Fluorescence

The toxicity characteristic leaching procedure (TCLP) is one test used by the U.S. Environmental Protection Agency (EPA) to determine if a waste material is hazardous; the TCLP test is widely used by the environmental testing community. The elements of concern for toxicity are arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. As an environmental forensic laboratory, the N...
