X-ray spectroscopy techniques have some advantages over other atomic spectroscopy techniques in the analysis of foods, for instance in not requiring significant sample preparation. Amongst these, TXRF has higher sensitivity and limits of detection in the ng range. The authors look at the analysis of a number of very different foods, including seafood, honey and vegetables.
Rigaku Corporation has announced the next generation NanoHunter II benchtop total reflection X-ray fluorescence (TXRF) spectrometer.
