Warning to DCP Users! The Influence of a Damaged Entrance Slit on the Optical and Analytical Performance in Direct-Current PlasmaAtomic Emission Spectrometry

Volume 45, Number 3 (April 1991) Page 498-500

Petersson, L.R.; Frank, A.


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.
