Wz. Tian et al., ROLE OF NAA IN THE CHARACTERIZATION OF SAMPLING BEHAVIORS OF MULTIPLEELEMENTS IN CRMS, Fresenius' journal of analytical chemistry, 360(3-4), 1998, pp. 354-355
Taking the advantage of the high precision and accuracy of neutron act
ivation analysis (NAA), sampling constants have been determined for mu
ltielements in several international and Chinese reference materials.
The suggested technique may be used for finding elements in existing C
RMs qualified for quality control (QC) of small size samples (several
mg or less), and characterizing sampling behaviors of multielements in
new CRMs specifically made for QC of microanalysis.
