  • Gas Chromatography: MCERTS Certification for Ambient Air Analysis on Benzene and VOCs

    Due to environmental issues, the world of gas analysis is evolving very rapidly. Governments set the rules to limit and control the environmental pollution through legislation. Volatile organic compounds (VOCs), often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

  • Case study : VOC analysis in ambient air by FID dectection - Complete system airmOzone

    Ozone concentration has been multiplied by 5 in the last century in the middle latitudes of the northern hemisphere from 10 PPB in 1874 to approximately 50 PPB today. This is an increase of 1.6% per year; the trend is probably higher (2.4% a year) over the last decades. (Chapter 1 of the International Geosphere-Biosphere Program - World Climate Research Program) In order to stop this global ...

  • Development of dry deposition velocity model for a typical medium level Indian city Karaikudi

    In this study, day and night dry deposition samples were collected with Eagle II arrangement of dry deposition plates. Karaikudi, one of the medium level city in India has been the chosen as area of study. Sampling locations were classified as zone1, zone2 and zone3. Wind speed was also recorded during sampling. Particle size was determined by using X–ray diffractometer (XRD). Relation between ...

  • Spectral Intensity Bioaerosol Sensor (SIBS): an instrument for spectrally resolved fluorescence detection of single particles in real time

    Abstract. Primary biological aerosol particles (PBAPs) in the atmosphere are highly relevant for the Earth system, climate, and public health. The analysis of PBAPs, however, remains challenging due to their high diversity and large spatiotemporal variability. For real-time PBAP analysis, lightinduced fluorescence (LIF) instruments have been developed and widely used in laboratory and ambient ...

  • Exhaust gas treatment by an atmospheric pressure microwave plasma

    A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

  • Characterisation of ambient benzene, toluene, ethylbenzene and m-, p- and o-xylene in an urban traffic area in Bangkok, Thailand

    Ambient Volatile Organic Compounds (VOCs) were examined in a heavy traffic urban area in Bangkok, Thailand, on focusing monoaromatic compounds of benzene, toluene, ethylbenzene, m-, p- and o-xylene (BTEX). Passive samplers were used to measure ambient BTEX concentrations in the environment close to very congested roads. Prior to the measurement, the validity of passive sampler performance was ...
