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.

Zinc telluride films doped with gadolinium (ZnTe:Gd)—made by laser ablation and deposition—have been characterized by X-ray photoelectron spectroscopy (XPS) to determine the molecular species of the elements in the material and their presence as intentionally formed contaminants.

Works of art often consist of multiple layers and can require several complementary techniques for complete analysis, and invasive sample preparation procedures and analysis techniques are not good choices. This interview with Dr. Karen Trentelman of the Getty Conservation Institute (GCI) in Los Angeles, California, discusses her research with X-ray fluorescence (XRF) spectroscopy for the study of cultural heritage materials such as paintings, sculptures, and illuminated manuscripts.

Determination of trace metals in oil and petroleum typically is based on ICP-OES methods, requiring signficant sample preparation and expensive instrumentation. This article presents an alternative method, based on the use of a handheld energy-dispersive X-ray fluorescence analyzer, that involves minimal sample preparation, uses authentic standards for calibration, gives low parts-per-million detection limits, and provides significant time and cost savings.
