FIELD: instruments for spectral analysis. SUBSTANCE: device has six electrodes which are located around circle and are connected to six-pole power supply which provides possibility to ignite high-voltage, low-current discharge between tips of electrodes. Axes of electrodes are located on cone surface which generatrix is at acute angle to axis of plasma torch. Axes of channels are located on articulated cone surfaces of tube and housing, in which lower part filter is rigidly mounted. Cylindrical surfaces, inner surface of housing and external surface of tube provide ring chamber in which radiators are located. Inner diameter of tube is less than distance between ends of opposite electrodes. EFFECT: increased functional capabilities. 1 dwg
