Optical Emission Spectrometers

Optical Emission Spectrometers determine analyte concentration via a quantitative measurement of the optical emission from excited atoms.  In an Optical Emission spectrometer, all atoms in a sample are excited simultaneously so they can be detected simultaneously using a polychromator with multiple detectors. This ability to simultaneously measure multiple elements is a major advantage of an Optical Emission Spectrometer compared to Atomic Absorption (AA) Spectrophotometer.
