Webb8 mars 2024 · Today we learn about how our instruments work. In Flame Photometry, the Flame Photometer is used to simultaneously detect and display five ions (K, Na, Li, Ca, and Ba) and to accurately determine the concentration of each within a given substance. Flame Photometry works by measuring the intensity of light emitted (measured using a …
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 ... WebbFlame Emission Spectrophotometry. Flame emission spectrophotometry is based on the characteristic emission of light by atoms of many metallic elements when given sufficient energy, such as that supplied by a hot flame. The wavelength to be used for the measurement of an element depends on the selection of a line of sufficient intensity to ...
