A device for automatic photoelectric control of the analytical gap for emission spectrographs

January 1, 1977

A photoelectric device has been built that automatically controls the analytical gap between electrodes during excitation period. The control device allows for precise control of the analytical gap during the arcing process of samples, resulting in better precision of analysis.
