US EPA Method 0061 provides procedures for the determination of Hexavalent Chromium emissions from incineration by elimination of Cr reduction between the nozzle and impinger by the collection of emissions samples in a recirculatory train where the impinger reagent is continuously recirculated to the nozzle.
Recovery procedures include post-sampling purge and filtration.
The TFC-47 Filter Column meets Method 0061 requirements for post-sampling filtration and recirculation to the nozzle.
