Third Harmonic YAG (355nm 15mJ Pulse) was also used in this work. While Steel is tested, the main point of this paper is to explore the use of the/azn Internal Standardization Method for analysis. The Internal Standarization Method used involves ratioing of trace element peak, to that of a nearby peak in abundance (and approximately constant concentration across the sample set).
