Trace Element Analysis Of Environmental And Clinical Materials Using Novel Instrumentation Based On X-Ray Fluorescence Spectrometry : New Capabilities For Public Health Laboratories, Kathryn G. Mcintosh

Legacy Theses & Dissertations (2009 - 2024)

X-ray fluorescence (XRF) spectrometry is a well-established analytical technique for determining the elemental content of many different materials. XRF has long been used for public health applications, particularly for identifying lead-based paint hazards. The primary advantage of XRF over other atomic spectrometric techniques is that it is nondestructive. In addition, little sample preparation is required, so results are obtained rapidly and at low cost. The principal aim of this study was to characterize the utility and reliability of current XRF instrumentation for use in the environmental health sciences. Interest in the use of XRF for detecting lead in children's toys …
