Atomic emission spectrometry analysis of metals and alloys using a two-jet arc plasma with spark sampling and calibration by solutions

Abstract

For the first time, the injection of solutions into the plasma of a two-jet arc plasmatron was used for the analysis of metals and alloys. Tandem calibration was used for quantitative chemical analysis by the TJP-AES method.

“…The second paper applied the technique to the analysis of steel samples including the reference materials UG-5K and UG-7K. 36 Agreement with certified values was very good. However, it was noticeable that precision was relatively poor.…”

“…Two publications by Kuptsov et al discussed the optimization of operational parameters 35 and the analysis of steels 36 using a two-jet arc plasmatron using spark ablation . The technique uses much higher power than an ICP (15 kW) and is used to analyse powdered solid samples directly, without recourse to dissolution procedures.…”

“…A two jet arc plasma with spark sampling and calibration was discussed at length in the Ferrous section. 35,36 A related paper, by Kuptsov et al , discussed its use for the analysis of dissolved solutions of brass samples. 39 Operating conditions were optimized and the effect of the concentration of matrix elements on the signal to background ratio of the analytes was determined.…”

“…2 Solids analysis 2.1 Direct methods 2.1.1 Arc and spark. In a series of articles, Kuptsov and coworkers [48][49][50] described the analytical capabilities of two-jet arc plasmatron (TJP)-OES using spark ablation. The optimised system was used to obtain accurate, reproducible analysis of metals and alloys with solution calibration.…”
