Abstract

A continuum source, multielement graphite furnace atomic absorption spectrometer was developed that employed a high-resolution echelle polychromator with charge-injection device (CID) detection. The detection system employed a new device, the CID 38, and camera control unit, the SCM5000E, providing unique new capabilities. A data acquisition and analysis scheme was developed for the prototype system, and the instrument demonstrated detection limits approaching that of commercial line source graphite furnace atomic absorption spectroscopy (GFAAS). However, the performance degrades in the ultraviolet due to decreasing source output.
