Abstract
A method for rapidly determining a sulfur level in materials, particularly molten metals or gases, the method comprising contacting a reference electrode made of a specific type of a metal and metal sulfide mixture with a sulfur-containing molten metal or gas serving also as a counter electrode through a sulfide solid electrolyte thereby measuring an electromotive force established between the electrodes. The working temperature of the molten metal or gas is also measured. These parameters measured are used to calculate a sulfur content based on a certain equation. The probe for carrying out the above method is also disclosed, which comprises a reference electrode made of a material having a certain sulfur potential, a mass of a solid electrolyte comprised of CaS and TiS.sub.2, the reference electrode being contacted with a molten metal or gas through the solid mass to form a cell, a means for measuring an electromotive force generated across the cell, and a means for measuring a working temperature of the molten metal or gas.
