Stack emission monitoring

The systematic measurement, characterization, and analysis of gaseous and particulate pollutants discharged into the atmosphere from industrial stacks, chimneys, or process vents. This process employs standardized sampling methodologies and advanced analytical instrumentation to quantify emissions such as particulate matter, volatile organic compounds (VOCs), sulfur oxides (SOₓ), nitrogen oxides (NOₓ), heavy metals, and other hazardous air pollutants (HAPs).

Our stack emission monitoring is conducted in accordance with internationally recognized U.S. EPA (USEPA) reference and conditional test methods, utilizing Direct Sensor Readout technology (Lancom III). The applicable standards include:

• USEPA CTM-030 / CTM-034 – Direct Sensor Readout (Lancom III)
• USEPA Method 10 – Carbon Monoxide (CO) Determination
• USEPA Method 6C – Continuous Measurement of Sulfur Dioxide (SO₂)
• USEPA CTM-030 / CTM-034 – Calculated Data (Lancom III-based)
• USEPA Method 1 & Method 2 – Sample and Velocity Traverses
• USEEPA Method 5 – Determination of Particulate Matter (PM)

USEPA Method 4 – Determination of Moisture Content in Stack Gas
