Abstract: Techniques and apparatus for measuring the concentration of elements in a solid metal sample by atomic absorption and fluorescence are described. A silica disc with an annular discharge-suppressing gap surrounding the sample area and an Oring seal are used to locate a surface of the sample for sputtering, and gas passages in the disc allow sputtered atoms to be swept into the body of a vacuum chamber for convenient analysis.
