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.

Calibration Plot

The accuracy of chemical analysis by flame atomic emission spectrometry is influenced by the methods used to obtain the calibration plot. Experimental data are treated by several different methods to obtain calibration plots, which are then used to determine the accuracy of each method. In general, log-log plots are shown to be more accurate than are linear plots, especially at the higher analyte concentrations where the emission is no longer directly proportional to concentration.
