This method is applicable for determining emissions of ammonia (NH3) from stationary sources. Samples are collected isokinetically in 0.1 N H2SO4 solutions using a Method 17 sampling train. The filter catch is typically not analyzed for ammonia. This method, previously known as EPA Method 206, has been renamed EPA Method CTM-027.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
