ABSTRACT:
Articles (14) are moved downwardly along a slideway (52) which includes a stop gate (50). The stop gate (50) is moved into the slideway (52) to stop the article (14). Then an instrument (44) is moved toward the slideway (52) and the article (14) to place the instrument (44) contiguous the article (14). The instrument irradiates the article (14). This radiation excites the elements in the article (14), causing them to give off their own characteristic x-rays. The energy of the characteristic x-rays identifies the elements and possibly also the element's concentration. Following the analysis the instrument (44) is raised and the stop gate (50) is lowered, allowing the article (14) to move forward along the slideway (52). Drill bits (14) are analyzed in this manner to differentiate between drill bits (14) of different hardness but identical geometric characteristics.
