Element offers a complete range of stack emissions testing, environmental inspection and consultancy services to help organizations achieve regulatory compliance for their industrial installations.


Operators with emissions to air from stacks and source releases are required to comply with Emissions Limit Values (ELVs) and Quality Assurance of CEMS as specified in their regulatory monitoring requirements (Permit, License, EU Directives e.g. Industrial Emissions Directive & Medium Combustion Plant Directive); independent, accredited stack emissions testing is essential for all organizations that wish to meet their responsibilities.


Our stack emissions testing and compliance services include:  


  • Periodic Compliance Monitoring
  • CEMS Calibration & Verification (EN 14181 QAL 2 & Annual Surveillance Test, US EPA RATA Protocols)
  • Accredited Stack Emissions Testing (ISO 17025, MCERTS)
  • In-House Accredited Laboratory Analysis (ISO 17025, MCERTS) of Stack Emissions Monitoring Samples
  • Training (Regulatory Compliance, EN 14181)
  • Investigative Testing, Process Optimization & Abatement Plant Efficiency Testing
  • Process Commissioning of New Plant
  • Offshore Emissions Monitoring
  • Air Quality Assessment & Dispersion Modelling (Air, Noise & Odor)
  • Environmental Noise Monitoring (Noise Investigation, Acoustic Camera)
  • Planning & Permitting Support Services


Our depth of knowledge, resources, regional coverage and experience allows us to provide a fast, customer focused service, high quality delivery, guaranteed turnaround and flexibility with a commitment to working safely in all our activities. We provide all types of stack emissions testing using manual reference and alternative methods, instrumental analyzers, and FTIR including;


  • Particulate Matter, PM10 & PM2.5
  • Combustion Gases (NOX, NO, NO2, N2O, SO2, CO, CO2, VOCs & TOC)
  • Trace Pollutants (Dioxins & Furans, PCBs & PAHs, Metals & Mercury, Hexavalent Chromium)
  • Acidic Gases & Vapors (HCl, HF, NH3, HCN, H2S, Sulphuric Acid Mist, Nitric Acid Vapor)
  • Organic Compounds (Specific VOCs, Formaldehyde & Aldehydes, Isocyanates, Oil Mist, Tar & Bitumen Fume)
  • Odor
  • Bioaerosols
  • Biogenic Fraction CO2


We provide stack emissions testing in a range of industrial sectors including; Energy from Waste & Incineration, Power Generation & Large Combustion Plant, Petrochemical Refinery & Offshore Oil & Gas, Renewable Energy & Landfill Gas, Cement & Lime, Mineral Processing, Chemical & Pharmaceutical, Food & Drink, Metals, Particleboard & Fibreboard, Automotive and Manufacturing.


All our stack emissions expertise is provided by highly competent and experienced individuals in line with national legislation, and our testing and inspection services are delivered in accordance with the international standards ISO/IEC 17025 and MCERTS in the UK & Ireland.

We are dedicated to providing complete compliance management solutions through both testing and consultancy services. Our goal is to help you achieve regulatory compliance and meet your Environmental goals, prevent exposure and support reducing emissions and improvement in Air Quality.
