Abstract: A glow discharge tube for atomic light-absorption analysis in which a hollow cathode for producing atomic light-absorption lines comprises a molded article of fine powder containing at least one metal element which produces the atomic lightabsorption lines, the article being molded without heating it whereby the dislocation of atomic distance remains in the crystalline lattice to improve the sputtering rate of the metal atom so that the density of metal atoms in the hollow of the hollow cathode is increased to enhance the light intensity of the atomic light-absorption lines.
