Many developments in the miniaturization of analytical instruments have enabled metal detection at extremely low concentrations, using techniques such as XRF, LIBS, and laserablation resonance ionization mass spectrometry (LA-RIMS). These new technologies are facilitating advances in areas such as space exploration, environmental studies, and pharmaceutical analysis.

Total reflection x-ray fluorescence (TXRF) spectrometry is an energy-dispersive x-ray technique that is used for elemental and chemical analysis, and is especially suitable for small-sample analyses. Ursula Fittschen, an assistant professor at Washington State University, is working on elemental microscopy and micro analysis. She has been using TXRF to analyze stainless steel metal release, and also airborne silver nanoparticles (NPs) from fabrics. Here, she describes the advantages and challenges of this technique.

As a fast, quasi-nondestructive analytical technique, X-ray fluorescence (XRF) spectroscopy is useful for a wide range of applications. To get a sense of the current breadth of XRF’s use and its potential growth in new areas, we asked a panel of experts to comment on the most important application areas for XRF, including the challenges involved and how XRF competes with other techniques.
