  • 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 ...

  • 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, ...

  • USEPA Method 8260C using the Tekmar Atomx Automated VOC Sample Prep System and a Thermo Focus/DSQ™ II GCMS

    The United States Environmental Protection Agency (USEPA) developed Method 8260 to determine the concentration of Volatile Organic Compounds (VOCs) in water and soil matrices. USEPA Methods 5030 and 50351 are used to prepare water, soil and waste samples for analysis by USEPA Method 8260. USEPA Method 8260 was recently updated from 8260B to 8260C2. In this study water and soil sample analysis ...

  • VOC Remediation Using HRC at Navy Base

    Site Summary Site investigations at a Naval Base in Long Beach, California revealed high contaminant levels of volatile organic compounds (VOCs) from a dry cleaning operation. In well MW-14-S4, the contamination levels of DCE, TCE and PCE reached 4,100 μg/L, 4,000μg/L, and 6,500 μg/L, respectively. The land use in this vicinity was primarily industrial and operations ceased by ...

  • Short distance modification of vehicular exhaust VOC fingerprint

    This work aims to investigate how volatile organic compounds (VOCs) emitted from vehicular exhausts behave in regard to their role in pollutant photochemical reactions at very short distances from their source. Results obtained with a receptor model of ambient VOC data measured at two sampling sites in the city of Rome, placed at different distances from the traffic line, have been compared with ...

    Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost-benefit based methods Water has become a vitally important resource.  Maintaining its quality and quantity and avoiding pollution are set to be ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Impact of Sampling Media on Soil Gas Measurements

    Abstract To evaluate the vapor intrusion pathway for a building and to assess the associated human health risks, soil gas samples near the building site and under the building foundation may be collected. In order to meet risk assessment goals, the analytical laboratory is often required to report compounds of concern for these soil gas samples down to the part per billion ranges or lower. ...

  • SPME/GC Analyses of Sulfur Gases and VOCs, Using a Carboxen/PDMS Fiber

    Sample extraction of sulfur compounds and VOCs by traditional methods can be difficult and expensive. Typically, sulfur analysis requires concentration of the gas using adsorbent tubes containing carbon adsorbents. Analysis by such means, however, requires the use of an expensive thermal desorption unit to heat the tubes before transferring the gases to a gas chromatograph. Analysis of VOCs ...
