Zusammenfassung:	Portable Energy-Dispersive X-Ray Fluorescence (XRF) analyzers have undergone significant improvements over the past decade. Salient advantages of XRF for elemental analysis include minimal sample preparation, multielement analysis capabilities, detection limits in the low parts per million (ppm) range, and analysis times on the order of 1 min. This article aims to stimulate interest in incorporating XRF into undergraduate chemistry lecture and lab settings.
