Abstract

The echelle grating of the optic section of the direct-current plasma (DCP) instrument produces two-dimensional spectra, which can be documented with the use of a photographic attachment to the instrument. By means of polaroid or other types of high-sensitivity photographic films, the spectra can be visualized and studied for qualitative analytical purposes. The usefulness of the photographic attachment for making photos of spectra has been reported previously.
