Abstract

In order to evaluate the analytical precision in low pressure laser-induced argon plasma emission spectrometry (LIPS), we conducted the determination of Ni in Fe-based alloys to consider the most suitable measurement condition, in particular, a gas pressure of argon and several measuring parameters for time-resolved observation. The selection of emission lines was an important factor to obtain a liner calibration curve depending on the concentration of Ni. The precision was generally inferior to analytical results in XRF and ICP-OES. However, the analytical value of Ni was obtained with good reliability, by averaging during replicate measurements. It was further shown the Ni content in Fe-Ni-X alloys would be determined by using calibration curves estimated from binary Fe-Ni alloys.
