Spectrometers for glow discharge optical emission spectroscopy that allow simultaneous monitoring of selected spectral ranges or the whole emission spectra.
Note:
GD-OES spectrometers mostly use the so called Paschen–Runge mounting, where the entrance slit, the curved grating and different detectors are aligned along the Rowland circle. Alternatively, Echelle spectrometers (see GD-OES spectrometers with simultaneous detection) are used, which use an Echelle grating in combination with a prism for wavelength separation.
