The vigi e-nose is an analyzer able to track VOCs, Sulfur compounds and other molecules such as ammonia for example. It allows to provide a rich global fingerprint to correlate with human sensory evaluation as dynamic olfactometry as example. It is possible to train the vigi e-nose with human sensory samples to study correlation with ASTM 679-E04 or EN 13725. As electronic nose, it provides chemical and olfactive fingerprint. The main differences are that vigi e-nose offers with single instrument : ...

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 ...

Laboratory instruments solutions for petrochemical and biofuel

Crude oil is a highly complex mixture of hydrocarbons. Through desalting, distillation, and conversion, it is transformed into fractions of higher-quality hydrocarbons such as paraffins, aromatics, naphthenes, and olefins. Different ratios of these so-called PIANO compounds are blended to yield different fuel and lubricant types. Increasingly, fossil fuels are blended with biofuels. Both blending and refining processes are demanding and require precise and reliable analysis. Regardless whether you deal with fossil ...
