  • What is a Volatile Organic Compound (VOC)?

    What is a Volatile Organic Compound (VOC)? Our products are known for monitoring many different gases, but if you look closely at the description of some of them, you will see that it mentions the acronym VOC. For those that don’t know what VOC means, it stands for volatile organic compound, and there are thousands of different ones produced and used in our daily lives. ...

  • 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 ...

  • Detection of volatile organic compounds in waste water

    A standard Hiden HPR-40 has been used for the detection of VOCs (volatile organic compounds) in water. This forms an important monitoring procedure for any installation that uses or produces such compounds and performs testing to help ensure that they do not impact on the environment. Such testing often forms mandatory government legislation for businesses. The data show the detection limits and ...

  • Fast analysis of semi-volatile organic compounds using PTV-GC–TOF MS

    The evaluation of semi-volatile organic compounds (SVOCs) in environmental matrices poses many challenges for the analyst, not least the vast number that may be encountered in any given analysis. In addition, analyte reactivity and the potential for multiple analytes to co-elute makes achieving the required method detection limits (LODs or MDLs) quickly and cost-effectively a formidable task ...

  • Electrical heating for the removal of recalcitrant organic compounds

    ABSTRACT This paper presents a remediation technology that combines electrical heating of the soil with extraction to achieve removal of vapour pressure sensitive compounds, such as chlorinated solvents, volatile and semi-volatile organic compounds, and heavier hydrocarbons. This technology is commercially known as the Electro-Thermal Dynamic Stripping Process (ET-DSP). As well the ...

  • Avoiding Sewer Fires with Vapor Space Organics Monitoring

    ABSTRACTRegulation of flammable gases released from wastewater discharges is facilitated by the use of the Vapor Space Organics test method. Such regulation can reduce the risk of a flash sewer fire, resulting damage and potential injury. The updated 2003 VSO process developed by Severn Trent Laboratories produced data that was equivalent to the 1990 VSO process developed and used by the ...

  • Rxi-624Sil MS Exceptionally Inert, Low Bleed Columns for Volatiles Analysis

    - Optimized selectivity for volatiles and polar compounds ensures good separations. - Highly inert columns improve accuracy and allow lower detection limits, even for active compounds. - Most thermally stable 624 column available; low bleed, fully MS compatible. While mid polarity 624 columns are widely used for analyzing polar analytes and volatile organic compounds (VOCs), not all columns ...

  • Oxygen Release Compound - Canada Case Study

    EHC-O Oxygen Releasing Compound - ES&E Magazine (May 2007) A whimsical comment by the author Michael McClary compels one to realize that more intuitive processes can be overlooked when considering technology’s abilities to improve our natural environments. He said: “Irrigation of the land with seawater desalinated by fusion power is ancient. It’s called rain.” In situ treatment of ...


  • Improved Purge-Trap/GC Analysis of Volatiles in Drinking Water by US EPA Method 524.2

    The VOCARB 3000 adsorbent trap is suitable for monitoring volatile organic compounds in drinking water samples, as well as in wastewater and hazardous waste samples.  This adsorbent trap meets the requirements of US EPA Methods 502 and 524.2.  Relative standard deviation values were less than 15% for all of the compounds listed, and less than 7% for most of the compounds.  Recovery ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • A Batch-Type Testing Method for Determination of Adsorption of Gaseous Compounds on Partially Saturated Soils

    As part of this study, a laboratory batch-type testing method has been developed for determination of the adsorptive characteristics and equilibrium adsorption coefficients for gaseous chemical species on partially saturated soils. The testing procedure was originally developed in support of in-situ tests at radioactive waste disposal sites in which relatively inert tracer gases are injected into ...
