LTL and
CLAMS do
radiocarbon dating by high resolution mass spectrometry only
for the samples which provide at least one milligram of
graphite after the removal of contaminants.
The standard precision in the measurement of 14C/12C
ratio is 0.5% for samples aged less than 2000 years old, which
means a standard deviation of ± 40 years. The inexactness in
the measurement may significantly vary according to the age of
our sample, generally decreasing for older samples. On request,
CEDAD does even high-precision measurements with a standard
deviation of 25 years.
CEDAD assures the accuracy of its services by the standard
measurements provided by international normative organizations
(like IAEA) and by comparing its own results with the ones
obtained in other countries.
Prices depend on the type of material and on the urgency of
measurement, according to the arrangements of the Dept. of
Innovation Engineering and of the board of directors of the
University of Lecce.
