Sample Preparation: The sample is typically dissolved in an appropriate solvent to create a solution. Nebulization: The solution is converted into an aerosol using a nebulizer. Atomization: The aerosol is introduced into a high-temperature plasma, where it is atomized and excited. Emission: The excited atoms emit light at characteristic wavelengths. Detection: The emitted light is detected and analyzed using a spectrometer to determine the elements present and their concentrations.
