With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
There are many types of stationary and mobile internal combustion engines that can run off gas or diesel fuels. Engines can be lean burning at a high air to fuel ratio (AFR) or rich burning at a low AFR. The exhaust stack gases from engines contain pollutant gases including CO, NO, NO2, NOx, and CxHy hydrocarbons as well as particulate matter. Measuring the engine exhaust emissions is important for engine tuning, performance optimization, safety, and proving emissions compliance to regulatory authorities.
Exposure to UFP due to air traffic has a growing attention. In the Netherlands several studies have been carried out on the largest airport, Schiphol. For mobile measurements NanoTracers were used in combination with more stationary equipment (eg SMPS). For the full report (in Dutch) see: http://www.rivm.nl/dsresource?objectid=rivmp:289756&type=org&disposition=inline&ns_nc=1.
Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.
