Element’s ISO 17025 UKAS-MCERTS-INAB- SAC-SINGLAS accredited Stack Emissions Testing, environmental inspection, and consultancy services help you achieve regulatory compliance, meet your environmental goals,  mitigate pollution and avoid legal actions. 


What is Stack Emissions Testing? 

Stack emissions testing, also known as stack monitoring or stack sampling, is a method of measuring and analyzing the emissions of various pollutants and chemicals being emitted into the atmosphere from industrial sources such as smokestacks, chimneys, and exhaust systems. This testing is crucial for you to monitor the environment and ensure that your industrial facility complies with limits outlined for permitted processes and government regulations, maintaining air quality standards. MCERTS accreditation is required in order to carry out stack emissions testing.


Key Benefits of Stack Emissions Testing and Monitoring  

  • Minimize your Operational Disruptions: Our strategic scheduling and the use of our efficient emissions equipment help you maintain your production schedules while staying compliant with environmental regulations.
  • Efficiency in your Self-Monitoring: Our audit training, like Operator Monitoring Assessment (OMA), prepares you for an Environment Agency audit visit and ensures effective and efficient audit representation.
  • Trusted Solutions for your CEMS: Element’s 300+ annual EN 14181 CEMS QAL2 and AST campaigns feed into a Technical Excellence Hub, offering the best advice and trusted solutions for your CEMS Quality Assurance and Verifications.
  • Customized Support for your Unique Challenges: You can count on our experience and expertise to address your specific emissions needs and solve complications on-site. 
  • Prove your Odour Compliance with Confidence: Many facilities are required to operate under an Odour Management Plan (OMP) as part of their Environmental Permitting Regulations. Element is UKAS accredited for European Odour Standard EN 13725:2003, allowing you to prove odour compliance with reliability.
  • Best tools for your Emissions Testing Requirements: We provide you with access to cutting-edge and specialized emissions testing equipment like APEX instruments, instrumental analyzers, FTIR and T-CEMS (Transportable Continuous Emissions Monitoring System). 
  • Streamlining your Data Management: Element handles equipment maintenance, calibration, and performance checks in-house, making sure you’re provided with accurate, reliable and efficient emissions data. 
  • Maritime Compliance Made Easy: International Maritime Organization (IMO) regulations have been tightened in recent years to limit air emissions from ships and other maritime vessels. Our ISO 17025 UKAS-MCERTS accredited emissions testing methods monitor maritime emissions highlighted in the MARPOL Annex VI Regulations, aimed at controlling pollutants such as NOx, SOx and CO2.


Decoding your Emissions Regulations Complexities 

Navigating emissions regulations and stringent quality standards, like MCERTS or ISO 17025, can be complex. With ISO 17025 UKAS-MCERTS-INAB- SAC-SINGLAS accreditation and MCERTS-certified emissions experts, we ensure accurate, reliable, and compliant testing, making your regulatory compliance responsibilities straightforward and pain-free.
