  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Development of on-line and field dual TD-GC-FID/MS for automatic and continuous Volatile Organic Compounds (VOCs) ambient air and odour monitoring

    Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from ng/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform using chromatographic ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • NASA campaign KORUS-AQ: IONICON PTR-TOF to monitor VOCs above Korea

    Team of the University of Innsbruck and an IONICON PTR-TOFMS aboard NASA research aircraft An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists ...

  • 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 on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Ambient air is polluted by many semi-Volatile and Volatile Organic Compounds (SVOCs and VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from pg/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform ...

  • Developpement of on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Significance of the Research: Ambient air is polluted by many VOCs coming from Petrochemical Industry. PAMS, Oxygenated or Halogenated VOCs can be found in many ranges of concentration between background and site fence line. These compounds are precursors of ozone and Industrial bodies need to identify them to be in compliance with the authorized limits and to improve their process. ...

  • Factors affecting the choice of VOC sensor

    VOCs (Volatile Organic Compounds) perform many vital roles as fuels, solvents, cleaners, feedstock, sterilants etc. However, they can be harmful to health and the environment, so it is often necessary to monitor their concentration. By definition, organic compounds contain the element carbon, and exhibit similar chemical properties, which is advantageous from a monitoring perspective. However, ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Solutions for Coating VOC & HAP Abatement

    Overview Our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate. One thing we do know for sure is that Carbon Dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. These days, many individuals and businesses alike are trying to ...
