Types of spectral interferences:
While a quantitative analysis using a standard calibration curve is carried out, the calibration plot of emission intensity vs concentration of the ionic species of interest is plotted. Like a curve shows deviations at the low and high concentration ends.
The following categories of spectral interferences might affect the accuracy of flame photometric determinations:
