emission spectroscopy
Quick Summary
Emission spectroscopy is a scientific method used in spectrochemical analysis to determine the elemental composition of substances. This technique involves exciting atoms in a sample using electrical discharges or flames. When these excited atoms return to their lower energy states, they emit light at specific frequencies, creating a unique spectral "fingerprint" that allows for identification of the elements present.1
The process involves vaporizing the sample, exciting its atoms, dispersing the emitted light into its component frequencies using a prism or grating, and then measuring the intensity of the light. Emission spectroscopy is highly sensitive, capable of detecting elements present in very small amounts, and can identify multiple elements simultaneously. This method is fundamental to understanding atomic structure and the interactions of light with matter.123
