The interference due to variabie concentration of sodium and its compensation by using internai standard eiement yttrium were investigated . It was ， ， ， found that the combination of robust conditions i . e . high power and iow carrier gas fiow rate and seiecting some ion iines with sum of the ionization and excitation energy more than 10 eV couid compensate for interference from sodium matrix using yttrium 437 .494 nm internai standard eiements .
