Types of interferences:
The various kinds of interferences encountered in analysis through flame photometry are:
Further, some other factors, such as viscosity, and surface tension of the solvent also affect the intensity of light emission, therefore contributing to erroneous results of analysis.
The main basic components of instrumentation for flame photometry are:
