WebbThe principle on which AAS is based is similar to FES. In AAS, however, the flame serves to dissociate the element from its chemical bonds and place it in a ground state at which it … WebbThis is the basic principle of flame photometry. A photocell detects the emitted light and converts it to a voltage, which can be recorded. Since Na+ and K+ emit light of different wavelengths (colours), by using appropriate coloured filters the emission due to Na+ and K+ (and hence their concentrations) can be specifically measured in the same ...
