Abstract
A device for optical emission spectroscopy comprising a chamber comprising an atomization source, at least one boost device configured with a radio frequency source to provide radio frequency energy to the chamber, and an optical detector configured to detect optical emission of species in the chamber is provided. In certain examples, a boost device may be used with a flame or plasma to provide additional energy to a flame or plasma to enhance desolvation, atomization, and/or ionization. In other examples, the boost device may be configured to provide additional energy for excitation of species.
