Spectroscopy Spotlight
Metals and metalloids, while essential to some living organisms, can, in high concentrations, be toxic. An understanding of how these metals and metalloids are accumulated and transported within plants and animals is possible with the use of synchrotron X-ray fluorescence (SXRF) microtomography. The technique is used in the imaging of major and trace element distributions within natural materials, nondestructively, and with high spatial resolution. Stefan Vogt of the Argonne National Laboratory in Lemont, Illinois, has been exploring the use of SXRF to detect metal content in biological and other systems. He recently discussed the various challenges, applications, and advantages associated with this technique. read more

Using this method, complete elemental recovery and removal of organic matrices can be achieved safely and up to 57 elements can be determined in oils with good accuracy and precision. The removal of organic matrices during digestion helps limit the formation of polyatomic spectral interferences and also improves instrument stability. read more
Many developments in the miniaturization of analytical instruments have enabled metal detection at extremely low concentrations, using techniques such as XRF, LIBS, and laser-ablation resonance ionization mass spectrometry (LA-RIMS). These new technologies are facilitating advances in areas such as space exploration, environmental studies, and pharmaceutical analysis. read more
