DEVICE FOR EMISSION SPECTRAL ANALYSIS Russian patent published in 1997 - IPC

FIELD: examination and analysis of substances. SUBSTANCE: device has chamber with electrodes of which at least one is manufactured for heating, electric current source connected to electrodes, and spectral device connected to chamber optically. Clearance between electrodes provides for current flow between the latter when current source voltage is below ignition threshold of independent discharge. Current flow is obtained with the aid of electrons simulated by heated electrode. Clearance itself is coupled to spectral device optically. EFFECT: higher results of analysis. 1 dwg
