Method 29 System
Method 29 System
The Method 29 determination of metal emissions from hazardous waste incinerators involves a modification of the Method 5 train. The sampling train is the same as a Method 5 particulate train with the addition of up to three impingers to enhance the collection of metals of interest. The impinger train requires the SB-4 impinger case, glass nozzle and probe liner, and a non-metallic union. The method has been validated for the collection of 17 different metals.

Description
Method 29 – Determination of Metals Emissions from Stationary Sources – EPA Literature PDF
*The standard glass filters are replaced with low background quartz filters. The impinger solutions are specific for different metals. Recovered samples are digested and appropriate fractions are analyzed by various means; inductively coupled argon plasma emission spectroscopy (ICPES), atomic absorption spectroscopy (AAS) or graphite furnace AAS, depending upon sensitivity required or the matrix effects on the specific analyte.*
