Analysis of high-alloyed steel by high-resolution ICP-OES

In high-alloyed steel trace and ultra-trace amounts of additives and impurities have great influence on performance and grade. Reliable trace detection has thus become the key objective of many laboratories entrusted with product control and quality assurance of steel products. For conventional ICP optical emission spectrometry the trace and ultra-trace analysis of high-alloyed steel samples poses a complex problems as more than 3300 registered Iron emission lines give rise to severe spectral interferences. Moreover, significant amounts of refractory additives like Molybdenum or Vanadium that contribute numerous emission lines, too, often further complicated the emission spectra. That is, for high-alloyed steel samples spectral interferences are infamous for impairing the quantification of trace elements like Phosphorus, Aluminum and Boron
