Lecture on alternatives to Oddy tests--addendum

The September 4, 2014 lecture presented by the Preservation Research
and Testing Division at the Library of Congress:

"Evaluating Storage Materials: Alternatives to the Oddy Test," given
by Dr. Eric Breitung (Research Chemist, Preservation Research and
Testing Division, Library of Congress)

About the lecture: The Library of Congress has a quality assurance
program for testing materials that come into contact with
collections in storage or on display to ensure those materials will
not harm collections.  The traditional Oddy test assesses the impact
of material off-gassing on collection items through the corrosion of
metal coupons, a result that does not necessarily correlate well to
the Library's primarily paper-based collections.  Dr. Eric Breitung
discusses research in the Preservation Research and Testing Division
that uses paper instead of metal as a sensor and multiple analytical
methods to assess the degradation level of the paper sensor.  Common
book and paper preservation materials such as book cloths, binding
boards, foams, and adhesives were subjected to accelerated aging in
the presence of Whatman filter paper and the traditional Oddy metal
sensors, then evaluated with ion chromatography (IC) and
ultraviolet-visible (UV-Vis) spectroscopy.  Of significant interest
was the analysis of corrosion products formed on the metal coupons
with x-ray diffraction (XRD).  Dr. Breitung discusses the assessment
of the impact of these specific products on collection materials to
better understand the often contradictory results obtained from the
Oddy test, and how a new test might better inform the paper
conservation community.
