How Flame Photometers are used in Chemical Analysis
Flame Photometer is used to quantify the concentration of Sodium and Potassium in the body. Basic Principle of Operation of a Flame Photometer When a sample is heated, the electrons are raised from the ground state to a higher state. The excited electrons are unstable and return to the ground state emitting photons of a…

Spectrophotometry Instrumental Method of Analysis
Principle of Spectrophotometry Spectrophotometry is based on the electromagnetic radiation in the visible, ultraviolet and infrared ranges. According to the Quantum theory; the energy states of an atom or molecule are defined and change from one state to another, therefore, they would require a definite amount of energy. If this energy is supplied from an…
