Mn. Gorlova et al., A NEW USE OF THE ADDITION METHOD IN THE DETERMINATION OF TRACE-ELEMENTS BY ATOMIC SPECTROSCOPY, Industrial laboratory, 60(12), 1994, pp. 714-715
A modified version of the addition method for the determination of tra
ce elements by atomic spectroscopy is proposed. In the modified method
, the mass concentration of an analyte is simultaneously determined in
several samples that are weight multiples of each other, using approp
riately proportioned amounts of reagents under identical conditions of
sample preparation and signal recording.
