The principle of flame photometry depends on

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 ...

JSPC IMA Notes HR 21 - Principle of flame photometry

WebbTheory: When a solution containing metallic salt is sprayed into flame, the solution dries out by leaving a fine residue of neutral atoms. These neutral atoms absorb the thermal energy of the flame and get excited to their higher energy state and thereafter return to ground state. During return to ground state, the excited atoms lose the ... WebbThe principle of flame photometer is based on the measurement of the emitted light intensity when a metal is introduced into the flame. The wavelength of the colour gives information about the element and the colour of the flame gives information about the amount of the element present in the sample. dickson county veterans coalition https://northeastrentals.net
