    Determination of TOC in stack

    PROBLEM: The industrial chimney's emissions of Volatile Organic Compounds (VOCs) are becoming issues of global importance and to have an accurate knowledge about how to test VOC turns into a strategic issue. VOC emissions are quantified and monitored according to standard EN 12619, using FID analyser which uses hydrogen and other reference gases in pressurized cylinder. Operators must then approach the sampling point, often placed several meters from the ground, climbing chimneys of industrial settlements with...

    Analysis of VOCs emissions from a car painting line

    During car manufacturing, Volatile Organic Compounds (VOCs) associated with the paints are emitted to the atmosphere. These are carcinogen, toxic and lead to tropospheric ozone formation. Therefore, VOC emissions must be reduced. With this aim, Chromatotec® airmoVOC C6-C12 (GC-FID analyzer) has been used to monitor VOC emissions from a car painting line. Indeed, it can measure concentrations ranging from very low (ppt) to high (ppm) level, so it is suitable for emission measurements. When coupled to MS...

    Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

    It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle...
