A method of analyzing elements of a metal melt contained in a melting vessel comprises the following steps: introducing an inert gas at a temperature in excess of 300.degree. C. laterally into a tube passing through a lateral wall of the melting vessel and opening thereinto; generating a laser beam; passing the laser beam through an adjustable first lens system; reflecting the laser beam by a mirror into the tube; guiding the laser beam through a quartz window which closes the tube; generating a plasma in the tube by focusing the laser beam by the adjustable first lens system onto the surface of the metal melt in the tube; guiding the light generated by the plasma through the quartz window to an adjustable second lens system; coupling the light by the adjustable second lens system with an optical waveguide; and introducing the light by the optical waveguide into a spectrometer.
