Analysis of Toxic Metals in Environmental and Consumer Product Samples
X-ray fluorescence spectroscopy (XRF) and flame atomic absorption (FAA) are two techniques we use to identify and quantify toxic metals such as lead in a wide variety of samples.
The XRF technique allows for quick, simultaneous identification of elements between atomic numbers of 11 (sodium) and 92 (uranium), with minimal sample preparation. Elements of high concentration can also be quantified using this technique.
For trace elements, FAA may also be used to quantify.
Specific projects involving these two techniques are (1) determination of lead content in recycled plastics materials, and (2) analysis of elements in environmental and grape vine samples from a local vineyard.
