SAMPLE MASK AND HOLDER FOR FLUORESCENT X-RAY ANALYSIS, FLUORESCENT X-RAY ANALYSIS OF SLAG

摘要

PROBLEM TO BE SOLVED: To provide a sample mask and holder for fluorescent X-ray analysis capable of preventing the drop of analytical precision caused by the surface unevenness of a sample, when a solid sample piece is directly subjected to fluorescent X-ray analysis, and a fluorescent X-ray analysis method for slag. ;SOLUTION: A sample mask 2 for fluorescent X-ray analysis has an opening part 6 for irradiating with a primary X-ray and taking out characteristic X-rays, and has the projected part 4 surrounding an opening part 6 on the surface opposed to the sample thereof, and a sample holder is formed by using this sample mask 2. Molten slag is bonded to the peripheral surface of a prismatic or plate-shaped sampler to be quenched, solidified and separated, and the smooth analytical surface of the obtained slag sample piece is brought into contact with the projected part 4 of the sample mask 2 to perform fluorescent X-ray analysis.;COPYRIGHT: (C)1999,JPO
