the identification and quantification of several metals in homogenous polymeric material using energy dispersive X-ray spectrometry in (ASTM F ). A Standard Operating Procedure of the U.S. Consumer Product Safety Commission allows the use of XRF for determining lead in polymeric materials, with certain limitations (CPSC-CH-E). In the present work, energy-dispersive X-Ray fluorescence (EDXRF) is used to determine the element composition of samples of Fucus vesiculosus. X-ray fluorescence analysis is a powerful technique for elemental analysis of environmental samples (, ). It is a fast, non-destructive analytical method,Cited by:
use of elementary analysis and analysis on plane surfaces with Philips PV wavelength dispersive X -ray fluorescence spectrofotometer. On the basis of these results the EDAX equipment was calibrated. In this wa y it became possible to carry out a quantitative analysis for bromine and antimony of samples not being shaped as plane surfaces. Elemental Analysis Using a Handheld X-Ray Fluorescence Spectrometer. The U.S. Geological Survey is collecting geologic samples from local stream channels, aquifer materials, and rock outcrops for studies. of trace elements in the Mojave Desert, southern California. These samples are collected because geologic materials can release a varietyAuthor: Krishangi D. Groover, John A. Izbicki.

X-ray standing wave analysis for bromine chemisorbed on germanium. M. Bedzyk *, G. Materlik * Corresponding author By combining the structure determining capabilities of X-ray diffraction with the chemical sensitivity of X-ray fluorescence, it was possible to measure the bonding geometry for a submonolayer of chemisorbed Br atoms on a real Cited by: cal data; however, energy dispersive x-ray fluorescence (ED-XRF) provides a more efficient means of data collection by using portable equipment that allows the investigator to take non-destructive, direct measurements. While undertaking ED-XRF analysis of mudstones, . The method is applicable to products or additives having chlorine contents in the range 0, 5 % (m/m) to 0, 0 % (m/m), and bromine contents in the range 0, 0 % (m/m) to 0, 0 % (m/m). Other elements do not generally interfere, although lead may interfere at contents above 0, 0 % .
