Stack Emissions Monitoring
NPL Stack Emissions monitoring teams are MCERTS certified and UKAS accredited. NPL is a Board Member of the Source Testing Association (STA) and provides advice on calibration and quality assurance. An emissions survey from NPL can be used for:
- Quantification of emissions in accordance with IPPC, LCPD and WID Directives
- Validation of routine Continuous Emission Monitors (CEM) to BS EN 14181:2004
- Turbine and burner optimisation
- Validation of emission abatement techniques
- Sample position suitability

All testing is completed to, CEN, ISO, BS or US EPA protocols. NPL staff are able to give extensive measurement advice and comprehensive data reporting, analysis and interpretation.
The measurement capabilities of the facility extend beyond that of traditional instrumentation and manual sampling techniques. NPL's advanced FTIR system enables simultaneous, high precision monitoring of multiple components in stack gas. The system is capable of making highly accurate measurements of gaseous HCl, NH3 and HF in the presence of water vapour and other interfering species.
