Protocols, pitfalls, and publishing for pXRF analyses: From “know how” to “best practices”

Portable X-ray fluorescence (pXRF) exists in a somewhat liminal state as a technique in the archaeological sciences. On one hand, pXRF is essentially energy-dispersive XRF (EDXRF) condensed to fit into a handheld instrument.
