ABSTRACT:
A glow discharge lamp for qualitative and quantitative spectrum analysis having a discharge chamber closable on the cathode side by an electrically conductive disk at cathodic potential in which, to increase the luminous intensity and the accuracy of the analysis, a ring magnet of permanent magnet material magnetized in axial direction for producing a magnetic field extending substantially in axial direction in the discharge chamber is provided and a control electrode which is insulated from the anode body is provided.
