In order to study matrix effects and efficiency of internal standardization with an axially-viewed ICP-AES system, a large number of elements with atomic lines in the 2.9–7.8-eV excitation energy range and ionic lines in the 7.7–16.5-eV energy sum range were selected and matrix effects were evaluated using a multichannel detector having a wavelength coverage in the range 167–785 nm. Na and Ca were...
