Abstract:
1. An atomic absorption spectrometer including: a monochromater; an optical path for receiving radiation from a source and for directing the radiation to the monochromater; a sample station in the optical path; the monochromater having an entrance slit and a diffraction grating; a detector for receiving radiation from the monochromater; and the monochromater being oriented such that the entrance slit is arranged transverse to the vertical so that an image of the slit at the sample station, if radiation passes from the detector along the optical path, is transverse to the vertical so that sample materials produced in a graphite furnace will move upwardly from a lower portion of the graphite furnace and across the transversely arranged image of the slit so that radiation emanating from the source and travelling along the optical path will pass through the sample material and be detected by the detector.
