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
