Apparatus for analysis of mercury or hydride formers by atomic absorption measurement

摘要

a device for the analysis of mercury or hydridbildnern by atomabsorptionsmessung contains usual means (10) for elimination of mercury or the hydridbildners from one sample to the production of quecksilberdampf or a volatile hydride. a linienemittierende light source (58) sends a meu00dflichtbu00fcndel (56) with the resonanzlinien of mercury or the hydridbildners.in a meu00dfku00fcvette (26), the quecksilberdampf or hydride is initiated. the meu00dflichtbu00fcndel (56) enters through the meu00dfku00fcvette (26) through it. a detector (60) of the meu00dflichtbu00fcndel (56) directly, without having to monochromator.in such a device for suppression of non-specific absorption, and the influence of the spectral purity of the light source means (66) for producing a magnetic field and a ausschaltbaren providedby taking advantage of the zeeman effect which a periodic relative shift of the emitted spectral of the light source (58) and the resonanzlinien of atomdampfes in the meu00dfku00fcvette (26) hervorrufbar.for the determination of mercury is a device for the enrichment of mercury provided through which the quecksilberdampf hindurchleitbar, with at least one wash bottle (14), a wash bottle (14) downstream trockenrohr (22) and a pipe (24) with a body (28) a amalgambildenden metal.
