• Spectroscopic carbon electrodes contain frequently small amount of fluorine as impurity, and special attention should be paid for detection and estimation of this element if spectrochemically analysed. 24 samples of domestic and foreign made carbon electrodes are tested by spectroscopic analysis using CaF-emission band spectrum (b. h. 5291A).<BR>Four of them had no trace of detectable fluorine and the arc was stable. They were fit for use. Other four samples contained some amounts of fluorine (0. 001∼0.1% F) but the arc was stable.<BR>In the rest of the samples fluorine was not detected but the arc was very unstable.<BR>The causes which affect the stability of the arc may be the graphitization-degree of the carbon and other impurities.
