Element offers a complete range of stack emissions testing, environmental inspection, and consultancy services to help organizations achieve total regulatory compliance for industrial installations.
Operators producing emissions to air from stacks and other source releases are required to comply with Emissions Limit Values (ELVs) and Quality Assurance of CEMS as specified in their regulatory monitoring requirements, such as EU Industrial Emissions (IED) & Medium Combustion Plant (MCP) Directives, US Clean Air Act, Permit & License monitoring requirements.
MCERTS stack emissions testing and monitoring
Element are the largest ISO 17025 UKAS-MCERTS accredited organization in the UK, Ireland and The Netherlands operating from 11 regional across offices with over 50 teams.
Key Features of our class-leading emissions service include:
- People - Largest pool of MCERTS certified emissions experts in the UK (Level II with all 4 Technical Endorsements).
- Geographic Coverage - Engineers based across 10 regional offices to quicken operations, maintain competitive rates and provide value for money.
- Accreditation - Largest scope of UKAS Accredited Tests in the UK covering all the main parameters but also other, less common, compounds including Chrome VI, Isocyanates, Siloxanes, Bioaerosols, Speciated VOCs such as Phenols and Cresols, Sulphuric Acid Mist, Odour, HCN, H2S along with other trace and bulk gas components.
- Centre of Technical Excellence – Each year we conduct over 300 EN 14181 CEMS QAL2 and AST campaigns and all this knowledge, practical experience and best practice is focused in our new hub with the aim of delivering the best possible advice and trusted solutions for CEMS Quality Assurance and Verifications.
- Calibration Workshop – We maintain, calibrate and performance check all of our sampling equipment ourselves. For example, over 60 FIDs, over 60 Horiba Combustion Gas Analysers, and around 70 Manual Isokinetic Sampling Systems. This gives us a greater understanding of how the equipment works leading to more accurate and repeatable emissions data.
- In-House Analysis of Samples by Element laboratories – Some stack emissions testing requires extractive.
- e-Mission Digitial Portal to manage all aspects of your emissions requirements through an on-line system designed by Element.
We provide independent, accredited stack emissions testing, which is essential for all organizations that wish to meet their regulatory compliance responsibilities.
Audit training
In addition to stack emissions testing and compliance services, Element also offers audit training e.g. Operator Monitoring Assessment (OMA) to prepare for an Environment Agency audit visit. Audit training can help ensure your audit will be carried out effectively and efficiently, resulting in an accurate representation of the standard of self-monitoring.
The Element advantage
We conduct more EN 14181 QAL2 and ASTs than anyone else in the UK. Our newly formed Centre of Technical Excellence acts as a hub to share best practice and knowledge from our vast experience conducting tests with the full spectrum of different types of CEM.
With this complex, technical emissions testing trust our Element experts and the number one provider of this service.
We have specialized in-house training programmes targeted at excellence in the details, intricacies and methods A, B & C for deriving calibration functions for EN 14181.
Our goal is to help you achieve regulatory compliance, meet your environmental goals, and support reduced emissions to improve Air Quality.
