Arsenic Determination App

ARSINE GENERATION
Designed for multiple arsenic determinations using a colorimetric assay as described in the 22nd Edition of Standard Methods for the Examination of Water and Wastewater, Method 3500-As B. Kimble Chase arsine generators conform to ASTM, USP, and EPA specifications.


• Glass beads may be added to the absorber tube to enhance the mixing of the generated gas through the silver diethyldithiocarbamate
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type 1 and ASTM E438, Type 1, Class A requirements

Overview: The lead acetate-impregnated glass wool is inserted above the Standard Taper 24/40 joint. 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 recorded on a colorimeter or spectrometer.
