Stack Emission Testing

APEX Environmental is well-resourced to perform source emission projects of any size and complexity. Our sophisticated state-of-the-art instrumentation, as well as a staff of experienced professionals, ensures a premier service for our clients.

Some indicators of when stack sampling at an industrial source is conducted, include:

  • to satisfy testing conditions described in facility permit and approvals
  • to develop accurate emission inventories and emission factors
  • to understand and adjust industrial processes
  • to determine pollutant impacts from specific sources

 STACK SAMPLING TEST METHODS

Stack sampling test methods follow procedures and techniques described in US-EPA source testing codes. There are numerous recognised test methods for measuring industrial stack emissions, of which APEX Environmental uses the following:

  • Method 1-5: Determination of particulate emissions from stationary sources
  • Method 6: Determination of SO2 emissions from stationary sources
  • Method 6C: Determination of SO2 emissions from stationary sources (analyzer method)
  • Method 7: Determination of NOX emissions from stationary sources
  • Method 7E: Determination of NOX emissions from stationary sources (analyzer method)
  • Method 8: Determination of sulfuric acid mist and sulfur dioxide
  • Method 10: Determination of carbon monoxide
  • Method 18: Measurement of gaseous organic compound emissions by GC
  • Method 23: Determination of dioxins and furans from stationary sources
  • Method 26: Determination of HCl emissions from stationary sources
  • Method 26A: Determination of hydrogen halide and halogen emissions
  • Method 29: Determination of metals emissions from stationary sources
