Chem Science carries a vast range of Arsine Generator as per USP, EP, Japanese, Pharmacopeia. Arsine generators are used for multiple arsenic determinations. A sample containing arsenic is placed within the flask and converted to arsine gas. Hydrogen sulphide is off from the sample because the gas is generated by lead acetate-impregnated glass fiber. The absorber tube contains diethyldithiocarbamate reagent to soak up the arsine gas, after which the final product will be transferred to a cuvette for data measurement on a colorimeter or spectrometer.
