Flame Photometry - an overview ScienceDirect Topics
WebbA traditional and simple method for determining sodium and potassium in. biological fluids involves the technique of emission flame photometry. This relies on. the principle that an alkali metal salt drawn into a non-luminous flame will ionise, absorb energy from the flame and then emit light of a characteristic wavelength as. 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 ... WebbThis interference needs to be controlled to attain good results of analysis. Some of the commonly encountered interference processes in flame photometry are: Spectral interferences, 2) Ionisation interferences, 3) Cation-anion interferences, Cation-cation interferences, and. Oxide formati on interferences. Flame Photometry (Chapter 4) 107. 4.2. c# showdialog topmost
