Accurate measurement of ozone precursor volatile organic compounds (VOC) can often be costly and labour intensive, with detailed knowledge required to set-up monitoring equipment and configure specialist data management. As a result, many EU Member States have opted to simply measure a restricted list of compounds, such as benzene, toluene, ethylbenzene and xylene isomers (BTEX). This is due to the relative ease with which they can be analysed using a conventional, single-column gas chromatograph. However, this approach is problematic as it can often lead to a lack of insight on the most potent ozone precursors (e.g. ethene) that remain unmeasured. This creates a gap in the knowledge required to inform major policy decisions.
Ricardo has an unrivalled track record in the robust and accurate measurement of ozone precursors, and the timely management and reporting of air quality data. Using our proprietary, market-leading, data-management system, MODUS VOC, our experts can effectively detect, measure and monitor all commonly reported VOCs, including those listed in Directive 2008/50/EC on ambient air quality and cleaner air for Europe (the Air Quality Directive).
