Nina Owczarek, Assistant Conservator at the Penn Museum, presents: "ZAP! pXRF at the Penn Museum" The Penn Museum's Conservation Department acquired a new portable x-ray fluorescence (pXRF) analyzer in 2011. Nina Owczarek, Assistant Conservator, describes what pXRF is, how we use this technology at the Penn Museum, and what we hope to learn from the data it provides. This conservation work is made possible through the generous support of the 1956 Otto Haas Charitable Trust.
