A solution-based inductively coupled plasma optical emission spectrometric (ICP-OES) method is described forelemental analysis with relative expanded uncertaintieson the order of 0.1% relative. The single-element determinations of 64 different elements are presented, withaggregate performance results for the method and parameters for the determination of each element. The performance observed is superior to that previously reportedfor ICP-OES, resulting from a suite of technical strategiesthat exploit the strengths of contemporary spectrometers,address measurement and sample handling noise sources,and permit rugged operation with small uncertainty.Taken together, these strategies constitute high-performance ICP-OES.
