The laboratory for instrumental neutron activation analysis at the Reactor Institute Delft, Delft University of Technology
uses a network of 3 gamma-ray spectrometers with well-type detectors and 2 gamma-ray spectrometers with coaxial detectors,
all equipped with modern sample changers, as well as 2 spectrometers with coaxial detectors at the two fast rabbit systems.
A wide variety of samples is processed through the system, all at specific optimized (and thus different) analytical protocols,
and using different combination of the spectrometer systems. The gamma-ray spectra are analyzed by several qualified operators.
The laboratory therefore needs to anticipate on the occurrence of random and systematic inconsistencies in the results (such
as bias, non-linearity or wrong assignments due to spectral interferences) resulting from differences in operator performance,
selection of analytical protocol and experimental conditions. This has been accomplished by taking advantage of the systematic
processing of internal quality control samples such as certified reference materials and blanks in each test run. The data
from these internal quality control analyses have been stored in a databank since 1991, and are now used to assess the various
method performance indicators as indicators for the method’s robustness.
