zeeman - atomic absorption spectrophotometer, magnetic device, and processes for the production of the means for the protection of the pole shoes and of the magnetic device for this purpose,

摘要

the invention concerns a zeeman - atomabsorptionsspektrophotometer with a heizeinrichtung (5, 6, 7, 8) for the atomization of the sample and a magneteinrichtung (17) for generating a magnetic flux in the atomized sample, the magnets (9, 9 ', 10) with polschuhen (11, 11') in a corresponding magneteinrichtung (17), which is characterized by that the polschuhe (1111 ') at least at its head. the heated sample opposite area with a thin keramikschicht (12, 12 ') are coated, and processes for producing these magneteinrichtung.$a by the financial polschuhspitzen is the erosion of polschuhe by chemically aggressive samples to ensure that the accuracy of the zeeman - atomabsorptionsspektrophotometer over long operating hours at high levels and can be kept stable.
