Atomic Emission Spectrophotometry.

Atomic emission spectroscopy (AES) uses quantitative measurement of the optical emission from excited atoms to determine analyte concentration.Analyte atoms in solution are aspirated into the excitation region where they are desolvated, vaporized, and atomized by a flame, discharge, or plasma.This ability to simultaneously measure multiple elements is a major advantage of AES compared to atomic-absorption (AA) spectroscopy.The technique of flame photometry is an application of atomic emission for quantitative analysis.Atomic emission Spectrophotometer is versaitle, highly sensitive and very selective.Atomic emission spectroscopy (AES) is one of the oldest techniques for chemical analysis, and is still widely used for rapid identification and analysis of elements contained within a sample.
