What is Hexavalent Chromium Emission Testing Method about?

1. This method provides procedures for determining hexavalent chromium (Cr+6) emissions from various stationary sources. A recirculatory sampling train is used to collect samples isokinetically and prevent reduction of Cr+6 between the nozzle and impinger. 2. Samples are collected in a recirculatory train where an impinger reagent is continuously recirculated to the nozzle. The impinger train samples are analyzed for Cr+6 using ion chromatography with a post-column reactor and visible detector. 3. Compo
