Atomic Spectroscopy

Reducing Interference in AES Signals

Description

Atomic emission spectroscopy (AES) can produce interfering signals when atoms and molecules in a flame or plasma emit overlapping light. High-temperature atomizers excite many species at once, including oxides, hydroxides, and flame combustion products. These extra emissions can make the analyte signal harder to read.

Transcript

Like AAS, atomic emission spectroscopy, or AES, is affected by spectral and analyte interferences, but the high atomization temperature of AES shifts the balance of their impact.

High-temperature atomizers excite a wider range of elements and produce complex emissions themselves, making spectral interferences arising from overlapping emis...
