UKAS Accredited Composition Analysis (for Odour)
Pinpoint the Source of Odour with High-Accuracy Laboratory Testing
UKAS Accredited Composition Analysis is a laboratory-based service that identifies the exact chemical compounds contributing to unpleasant or harmful odours. This service goes beyond simple sniff tests — it quantifies specific gases such as ammonia, hydrogen sulphide, and volatile organic compounds (VOCs) using advanced analytical methods. The testing is fully accredited under UKAS (ISO/IEC 17025) standards, ensuring defensibility in legal, regulatory, and public contexts.
Used by site operators, regulators, and consultants alike, this service helps diagnose persistent odour problems, support enforcement action, or develop targeted mitigation plans.
Why It Matters — and What Can Go Wrong
When communities complain or permit officers come knocking, vague explanations don’t cut it. Without chemical proof of what’s causing the odour, you risk:
-
❌ Misidentifying the source — leading to wasted time and ineffective fixes
-
⚠️ Permit breaches or enforcement notices
-
📣 Escalating complaints and reputational fallout
-
🧾 Failure to meet Environment Agency or local authority demands
Unlike subjective odour assessments, this analysis gives concrete evidence — showing which substances are present, at what levels, and whether they exceed thresholds for nuisance or safety.
What’s Analysed
-
Key Odorous Gases – ammonia, hydrogen sulphide, mercaptans, VOCs
-
Complex Mixtures – chemical fingerprints from waste, food, industrial or agricultural sources
-
Sampling from Air, Emissions or Materials – depending on investigation needs
How It Works
-
Field sampling using sorbent tubes, gas bags, or canisters
-
Laboratory testing using GC-MS (gas chromatography–mass spectrometry) or FTIR
-
Quantified concentrations provided in ppm or mg/m³
-
Accredited results suitable for use in legal or planning submissions
