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.
