摘要

A fluorescence X-ray analyzer comprises a detection unit (6) for fluorescence X-rays, which are emitted from a test piece (1), and a primary collimator (10) located between the test piece and the detection unit. The primary collimator has a wall adjacent to the test piece, which is stepped to form openings of varying dia.. The smaller the opening, the closer it is to the test piece.
