Frequently Asked Questions

• Why is stack emission testing and sampling important?
  • To ensure compliance with mandatory emission standards, reduce environmental impacts, and maintain safe working conditions in accordance with Ministry of Environmental Protection requirements.
• Which methods are used for stack testing?
  • Testing is performed using American and European standard methods such as EPA and EN, as well as additional methods approved by the Ministry of Environmental Protection.
• How is the sampling process carried out in practice?
  • Sampling is conducted according to an approved plan, using advanced and calibrated equipment, by skilled field teams operating in compliance with safety procedures and regulatory requirements.
• Does the laboratory also perform the analytical testing?
  • Yes. Following field sampling, samples are transferred to an accredited analytical laboratory for analysis using internationally recognized standard methods to generate accurate and reliable data.
• Which pollutants can be measured in stack emission testing?
  • A wide range of pollutants can be measured, including particulates, metals, organic compounds (VOC, SVOC, PAH), combustion gases (SO₂, NOₓ, CO), mercury, aldehydes, acids, halogens, and more—according to EPA and EN methods.
• Do you perform QAL-2 and AST calibration for continuous monitoring systems?
  • Yes. CEMS calibration is performed in accordance with EN 14181 and the Ministry of Environmental Protection procedure for continuous monitoring system calibration.
• What does the final report provided to the client include?
  • The report includes full results analysis, comparison with regulatory limits, professional recommendations, and guidance on steps for emission reduction and improved compliance.
