Overview

The use of Handheld XRF has become indispensable in archaeological research.  The portability and ease of use allows for on-site and in-lab elemental investigation of a wide range of materials.  While the use of Handheld XRF has become established practice in obsidian sourcing, the analysis of archaeological ceramics has gained increased attention.  Traditionally, quantified compositional analysis of ceramic for provenance determination has been typically performed using neuron activation analysis (NAA) or inductively coupled plasma-mass spectrometry (ICP-MS).  However, the use of Handheld XRF for similar work requires the development of calibrations, presenting challenges based on the physical qualities of the material and X-ray physics. 

Presented here will be a review of compositional analysis by Handheld XRF, with particular focus on the challenges posed by archaeological ceramics.  The webinar will introduce approaches to robust analysis and evaluation of data.  In addition, an introduction to the calibration process will be presented, including suggestions for best practices that can be implemented by researchers interested in quantitative analysis of archaeological ceramics.

There will be a 15 minute Q&A live session where our experts will answer your questions.
