Abstract
An apparatus and method for detecting cadmium using optical emission spectroscopy is provided. The apparatus contains a system which uses optical emission spectroscopy which is programmed and calibrated to detect the presence of cadmium in PPM. The system is calibrated using test samples which have been prepared with a lead/cadmium matrix material having at least one iron based electrode integrated therein.
