用于多价砷的测定。
Designed for multiple arsenic determinations. A sample containing arsenic is placed within the flask and converted to arsine gas. Hydrogen sulfide is removed from the sample as the gas is generated by lead acetate-impregnated glass wool packed within the scrubber cavity. The absorber tube, containing the reagent silver diethyldithiocarbamate, absorbs the arsine gas and forms a red complex. This product is transferred to a cuvette, and its visible spectrum is then recorder on a colorimeter or spectrometer. Size 12 pinch clamp for 12/2 joint between the scrubber and absorber tube is available as an accessory.
