Abstract: The present invention belongs to a chemical analysis method, and more particularly relates to a method for simultaneous determination of Si, Mn, P and Cr in GCr15 by using a plasma spectrometer. Its features include: sample, sample, volume, ICP determination and working curve of the drawing steps. The method comprises the following steps: simultaneous determination of Si, Mn and P in GCr15 by using an equal sub-body spectrometer in the same mother liquor by using a mixed acid of concentrated perchloric acid and nitric acid to decompose and dissolve samples in a low temperature,
