PROBLEM TO BE SOLVED: To enable on-line instruction to smelting operation by subjecting the surface of a solidified slag adhering to a hollow prismatic quenching body in contact with the quenching body to fluorescence X-ray spectroscopy and speedily and accurately analyzing it. SOLUTION: A hollow prismatic quenching body 1 is supported by a paper tube 4, and a slag separating material 2 is applied to the periphery of the hollow prismatic quenching body 1 to form a smooth surface. In addition, the hollow prismatic quenching body 1 is a prism of, for example, 3 mm in thickness with a side of approximately 50 mm in consideration of easiness in handling a sampler at an operation site and further obtaining a smooth and flat sample. After bringing a molten slag into contact with the surface of the hollow prismatic quenching body 1. the hollow prismatic quenching body 1 is immediately pulled up, and the contact surface of the slag with the quenching body 1 is prepared as an analytical surface of fluorescence X-ray spectroscopy. In considering that the analytical depth in fluorescence X-ray spectroscopy is a fewμm, there is no problem at all in quenching into a glass form in this range. Therefore, it is possible to use the hollow prismatic quenching body formed of a metal plate relatively thin in thickness.
