WebAtomic-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. WebBoth methods resemble the flame method of emission spectroscopy ( i.e., a method that uses flame as the energy source to excite atoms) in that a solution of the sample is usually vaporized into a flame of hydrogen or acetylene in air or oxygen.

Web14 feb. 2024 · Flame photometry is a process wherein the emission of radiation by neutral atoms is measured. The neutral atoms are obtained by the introduction of the sample into the flame. Hence the name flame photometry. Since radiation is emitted, it is also called flame emission spectroscopy. Flame photometer working principle WebIn flame emission spectroscopy, the electrons in the analyte atoms are excited by the thermal energy in the flame. Thus the sample is the source of photon emissions through relaxation via resonance fluorescence (Section 1.2.2). Note that this results in emission systems that are only single beam in design.
