Emission Testing Services

APEX Emission Testing is proud to present our customers with the following point & mobile source emission testing services:

Isokinetic Stack / Duct Sampling Services (Particulates, Aerosols and Mists)

Apex Emission Testing utilises US EPA Sampling and Analytical Methodology to accurately determine concentrations and mass flow rates of process, or combustion related acivities.
  • Temperatures and Pressures (static and velocity).
  • Stack gas molecular weight.
  • Stack gas moisture content.
  • Volumetric flow rates.

    • Concentrations and mass flows of:

  • Acids (Organic and Inorganic).
  • Dioxins and Furans (PCDD/PCDF).
  • Metals - Antimony (Sb), Arsenic (As), Barium (Ba), Beryllium (Be), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Lead (Pb), Manganese (Mn), Mercury (Hg), Nickel (Ni), Phosphorus (P), Selenium (Se), Silver (Ag), Thallium (Tl), Zinc (Zn).
  • Oil Mists (Vegetable, Mineral etc.).
  • Particulates (Total PM, PM2.5, PM10).

Non-isokinetic Stack / Duct Sampling Services (Gases and Vapours)

Apex Emission Testing utilises US EPA Sampling and Analytical Methodology to accurately determine concentrations and mass flow rates of process, or combustion related acivities.
  • Temperatures and Pressures (static and velocity).
  • Stack gas molecular weight.
  • Stack gas moisture content.
  • Volumetric flow rates.

    • Concentrations and mass flows of:

    • Carbon Dioxide (CO2)
    • Carbon Monoxide (CO)
    • Fluorides (Total F as HF)
    • Hydrogen Sulphide (H2S)
    • Nitrous oxide (NO)
    • Nitrogen Dioxide (NO2)
    • Polycyclic Aromatic Hydrocarbons (PAH's)
    • Sulphur Dioxide (SO2)
    • Volatile Organic Compounds (VOC's)
