Advancing the application of pXRF for animal samples. [PDF]

PLoS One
Portable x-ray fluorescent (pXRF) technology provides significant opportunities for rapid, non-destructive data collection in a range of fields of study. However, there are sources of variation and sample assumptions that may influence the data obtained, particularly in animal samples. We used representative species for four taxa (fish, mammals, birds,
