Source‐level extractive systems remove gas directly from the stack or duct, filter out particulate matter, and transport the gas for analysis. Three types of source‐level extractive systems are marketed commercially:

1 Hot/wet systems (Figure 3‐1)

2 Cool/dry systems with conditioning at the probe (Figure 3‐2)

3 Cool/dry systems with conditioning at the CEM system shelter (Figure 3‐3)
