Determination of Sulfur Content in Steel by Laser-Produced Plasma Atomic Emission Spectroscopy

Ana Gonzcález, M.C. Reyes Ortiz, José Campos

Abstract

Sulfur content in steel samples has been determined by laser-produced plasma atomic emission spectroscopy with the use of a Q-switch Nd: YAG laser. With the use of time-resolved spectroscopy employing an OMA III (EG&G) as detector, a detection limit of 70 ppm and a precision of 7% have been obtained. Calibration curves are linear, and no noticeable matrix effects have been observed.
