When monitoring volatile organic compounds (VOCs) and total hydrocarbons (THC) in regulated industries, accuracy isn’t optional — it’s a legal and operational necessity. Whether you’re managing a waste incinerator, a thermal oxidiser, or a medium combustion plant, your gas analysis system must meet strict performance and certification standards.
At Signal Group, we’ve engineered the SOLAR CEMNEX to not only deliver world-class VOC measurement but to do so in full compliance with the industry’s most stringent certifications — including MCERTS, EN14181, and EN15267.
Here’s why certification matters — and how the CEMNEX helps you meet your obligations with confidence.
What Is MCERTS?
MCERTS is the UK Environment Agency’s formal approval scheme for emissions monitoring equipment. It certifies instruments that meet the required performance standards for environmental reporting and regulatory compliance.
To achieve MCERTS, systems must undergo rigorous third-party testing (e.g. by TÜV) to prove:
EN Standards That Matter for VOC Monitoring
EN14181 – Quality Assurance of CEMS
This standard defines the quality assurance framework for continuous emissions monitoring systems (CEMS) in industrial settings. It outlines three key phases:
- QAL1 – Instrument performance testing and certification
- QAL2 – On-site calibration against a reference method
- QAL3 – Ongoing quality assurance using control charts and drift checks
The SOLAR CEMNEX is designed with full QAL1 readiness, making it ideal for regulated installations where VOCs or THC must be continuously monitored and reported.
EN15267 – Performance Standards for Automated Measuring Systems
This standard specifies the minimum performance criteria for automated emissions monitoring systems used to demonstrate compliance with EU directives, including the Industrial Emissions Directive (IED).
It covers systems used for measuring pollutants such as:
- NOx
- SO₂
- CO
- VOCs (as THC or NMHC)
To meet EN15267, systems must include certified components and demonstrate consistent measurement capability across operational conditions — exactly what the SOLAR CEMNEX delivers.
EN12619 – Performance standard for measurement of VOCs using Flame Ionisation Detectors
EN 12619 is the European standard for measuring total volatile organic compounds (TVOCs) in waste gases using a flame ionisation detector (FID). It ensures instruments are designed and tested to deliver accurate and reproducible VOC measurements for emissions monitoring.
In meeting EN 12619, the Solar CEMNEX measures VOCs accurately and reliably under real stack conditions. It demonstrates precision, stability, and resistance to interferences while passing defined performance and validation tests.
Why Full-System Certification Matters
Many VOC monitoring setups only certify the analyser. But compliance — especially under EN15267 and EN14181 — demands that every part of the system maintains integrity, from gas extraction to data output.
That’s why the SOLAR CEMNEX stands out.
It is the only turnkey FID system with MCERTS certification covering:
- The S4 SOLAR analyser
- The 363SM heated sample probe
- The heated sample line (up to 30m)
- The automated calibration system
One supplier. One system. One certification path.
Built for Real-World Compliance
From high-temperature incinerators to VOC-rich RTOs and solvent recovery operations, the CEMNEX is designed for performance under pressure:
- Certified at 15, 30, and 500 mg/m³ THC
- Fully automated operation with remote access
- Zero-air generation, fuel changeover, multipoint sampling and purge/blowback options
- Dual-detector option for simultaneous THC/NMHC measurement
- Compliant with ISO 25140 for NMHC monitoring
This makes it ideal for regulated environments under:
- Industrial Emissions Directive (IED)
- Medium Combustion Plant Directive (MCPD)
- Environmental Permitting Regulations (UK)
Conclusion
Choosing a VOC monitoring system with proper certification isn’t just about ticking boxes — it’s about ensuring data integrity, audit-readiness, and future-proof compliance.
The SOLAR CEMNEX is MCERTS-approved, QAL1-ready, and fully aligned with EN14181 and EN15267 — delivering confidence where it counts.
