3 Method summary

The sample was measured for melting clean up, melted ingots after sampling, were reduced into ingots and ash representative samples, two kinds of sample points Do After digestion, after constant volume digestion solution by the carrier gas into the plasma, the wavelength corresponding to each analyte intensity, determined from the standard curve content.
