Single-element solution comparisons with a high-performance inductively coupled plasma optical emission spectrometric method

A solution-based inductively coupled plasma optical emission spectrometric (ICP-OES) method is described for elemental analysis,vith relative expanded uncertainties on the order of 0.1% relative. The single-element determinat ions of 64 different elements are presented, with aggregate performance res ults for the method and parameters for the determination of each element. T he performance observed is superior to that previously reported for ICP-OES , resulting from a suite of technical strategies that exploit the strengths of contemporary spectrometers, address measurement and sample handling noi se sources, and permit rugged operation with small uncertainty. Taken toget her, these strategies constitute high-performance ICP-OES.
