Application of PXRF on the archaeology and cultural relic study

XRF is an accepted and well understood method used in Museums. When using HH XRF or Portable XRF, the user needs to understand the constraints which physics puts on the measurement. The biggest question here is how to assess if the sample is homogeneous and suitable to give the user a “correct” answer.

Over the past decade, Alexander and his team have given over 300 workshops in Museums and Universities around the world including many world class institutions. The team has a very broad and deep technical knowledge of the challenges facing curators and conservators of very diverse collections and materials and is currently actively working on several applications.

The talk will cover and relate concepts such as the analyzed layer, grain size and matrix to applications and instrumentation. With this the user will be aware of data quality, especially when expanded into instrumentation and data reduction calibration method. A hands on workshop could be provided for those interested students and professors after the talk.

Jiyan Gu

Jiyan Gu is an application scientist working at Bruker Elemental。 He is now responsible for application development and technical support for China. He received his B.S. in chemistry from Nanjing University, China and Ph.D. in analytical chemistry from Wake Forest University，U.S.A.. Dr. Gu’s PhD study included developing field portable atomic spectroscopy device and applications development of AAS and ICP-OES. After graduation, Dr. Gu worked as a Postdoctoral Fellow at the W.M. Keck Center for Instrumental and Biochemical Comparative Archaeology, Millsaps College. During his postdoc study, he applied his analytical chemistry expertise to the solution of complex problems in archaeology (Maya and Albanian).
