An atomic emission spectrometer which allows simultaneous high-precision digital recording of the ultraviolet spectrum has been developed. The instrument employs both a custom-built echelle spectrometer and a custom-built slow-scan charge injection device (CID) based detector system. The system is capable of measuring the wide dynamic range of signal intensities associated with plasma emission sources, and sensitivity is comparable to that of photomultiplier-tube-equipped instruments. Unprecedented speed and flexibility for elemental analysis are provided by the ability to display background-subtracted emission spectra and to have the computer assist in spectral line identification.
