  • A Guide to BFB Tuning for VOC Analysis

    All US EPA methods for volatile organic compounds (VOCs) require that specific GCMS tuning criteria be met before running a calibration curve or analyzing actual samples. The GCMS is tuned using the traditional tuning compound, PFTBA (perfluorotributylamine), and the tune is evaluated every 12 hours by injecting BFB (4-bromofluorobenzene) and measuring the relative intensity of key mass ...

  • Case study N°AA7 – Ambiant air monitoring – VOC Purge & trap

    Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec Solutions Chromatotec has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • A Comparison Between EPA Compendium TO-15 and EPA MEthod 8260B for VOC Determination of Soil Gas

    ABSTRACT Evaluations of vapor intrusion pathways of chemical contaminants often include soil gas measurements to assess the potential for indoor inhalation. No longer just a screening tool, soil gas measurements are requiring a level of quality and defensibility which should be incorporated in soil gas analytical protocols. While both EPA Compendium Method TO-15 and EPA SW-S46 Method 8260B ...

  • 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 ...

  • Investigation of the effects of temperature and sludge characteristics on odors and VOC emissions during the drying process of sewage sludge

    Sludge drying is a necessary step for sludge disposal. In this study, sludge was collected from two wastewater treatment plants, and dried at different temperatures in the laboratory. The emission of odor and total volatile organic compounds (TVOCs) during the sludge drying process were determined by an online odor monitoring system. The volatile organic compounds (VOCs) in off-gas were analyzed ...
