Instrumental neutron activation analysis was
used to evaluate the between bottle homogeneity and the
minimum sample intake of a bovine kidney candidate
reference material. The mass fractions of ten inorganic
constituents were determined, obtaining satisfactory
homogeneity results for all of them. Statistical analysis of
the results was performed using a one way analysis of
variance and multivariate techniques were applied as
complementary techniques, confirming the usefulness of
these techniques for homogeneity assessment.
