Atomic Emission of Chlorine: Spectra from 200 to 900 nm by Sealed Inductively Coupled Plasma-Atomic Emission Spectroscopy

Abstract

Eighty-seven atomic chlorine lines and chlorine molecular spectra emitted in the 200–900 nm wavelength range are identified in a pure chlorine discharge generated at atmospheric pressure in a sealed inductively coupled plasma. Only small quantities of chlorine are needed for spectral evaluation because the flow rate is typically less than 20 mL/min.
