Workshop on XRF

The Foundation of the American Institute for Conservation of
Historic and Artistic Works presents:

"Quantification and Calibration"
Advanced workshop
Art Conservation Department
SUNY Buffalo State
Buffalo, New York
January 11-14, 2016

Instructors:  Dr. Aaron Shugar and Arlen Heginbotham

Registration Fee:

    $350 AIC members
    $500 non-members (includes refreshment breaks and lunches)

Limit 10 participants.  Space is limited, so early registration is
strongly encouraged.

Attendees of this course will learn about the various methods used
for quantification of XRF data.  In particular they will learn about
the statistics behind calibration, the methods used for calibration,
how to calibrate their specific instruments, what would be required
if they decided to create their own started reference materials, and
what they can expect from a calibrated system.

Although many conservation professionals are familiar with basics of
X-ray Fluorescence (XRF) analysis, more complex issues, such as
advanced data interpretation and system calibration for
quantification, are often misunderstood, or not understood at all.
This course will help attendants develop their skills with basics of
quantification, give them tools to calibrate a Bruker Tracer XRF
system correctly, have discussions on how limits of detection and
limits of quantification are calculated, and provide alternative
quantification solutions.  We will have experts in the field give
demonstrations and give participants the opportunity for time in the
lab to work with instrumentation along with these experts.
Reference sets (CHARMS) and sample collections from the Buffalo
State College Art Conservation Department will be used to calibrate
instrumentation.  This course is designed specifically for
conservation professionals with basic understanding of XRF.
Attendants are expected to bring their instrument with them so that
the calibrations build can be taken back to their institutions for
use.

Course Outline

Day one

    Lecture: Methods of Quantification

    Lecture: Determining Limits of Detection, Limits of
    Quantification, and error calculations

    Lab session: Collecting data from CHARMS set to be used for
    calibration

Day two

    Lecture on Bruker software used for calibration and the methods
    used to create a specific calibration

    Lab: Starting to build a calibration from the CHARMS set

Day three

    Lecture on pyMCA Theoretical modeling software for
    quantification

    Lab: Data collection of unknown samples and using pyMCA software

Day four

    Lecture: Continue with pyMCA and review collected data -
    discussion of interlabratory studies and the issues related to
    variable data collection

    Lecture:  Creating your own standard reference materials -
    options and suggestions.

    Summary of course and review of process.

Instructors:

    Dr. Aaron Shugar is the Andrew W. Mellon Associate Professor in
    Conservation Science in the Buffalo State College Art
    Conservation Department.  He has a Ph.D. in Archaeometallurgy
    from University College London and his work in the analysis of
    archaeological metals and glass has taken him around the globe.
    Aaron's main interest is in historic technologies and he has
    added hand-held XRF techniques as well as 3-D imaging scanning
    technology to his course work at Buffalo State to help graduate
    students gain a better understanding of the materials they are
    working with.  He is one of the leading experts in the field of
    handheld XRF technology and has given lectures across the
    country and Canada in addition to being widely published on the
    subject.

    Arlen Heginbotham received his A.B. in East Asian Studies from
    Stanford University and his M.A. in Art Conservation from
    Buffalo State College.  He is currently Associate Conservator of
    Decorative Arts and Sculpture at the Getty Museum.  Arlen's
    research interests include the use of X-ray fluorescence
    spectroscopy as a tool for studying copper alloy artifacts, the
    history of metallurgy, the history and analysis of 17th century
    East Asian export lacquer, and microscopic and chemical wood
    identification.

This program is supported by funding from the Foundation of the
American Institute for Conservation of Historic and Artist Works
Endowment for Professional Development, which was created by a grant
from The Andrew W. Mellon Foundation and donations from members of
the American Institute for Conservation and its friends.  Courses
are made possible with the assistance of many AIC members, but no
AIC membership dues were used to create or present this course.

Without this support, the registration fees would be approximately
$800.
