  • Differentiating Polychlorinated Biphenyls (PCB’s) by GC / FID / ECD

    The analytical chemistry of PCB’s is rigorous, demanding the highest quality in sample preparation and analytical technique. Insufficient sample extraction and inappropriate methods of sample clean-up are the most common sources of error in PCB analysis, which causes significant interference in the chromatography. However, even in relatively clean samples the problem remains to confidently ...

  • Field survey of Canadian background soils: Implications for a new mathematical GC‐FID approach for resolving false detections of petroleum hydrocarbons (PHCs) in clean soils

    The Reference Method for the Canada‐Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil provides laboratories with methods for generating accurate and reproducible soil analysis results. The CWS PHC Tier 1 generic soil quality guidelines apply to four carbon ranges/fractions: F1 (C6‐C10), F2 (C10‐C16), F3 (C16‐C34) and F4 (>C34). The methods and guidelines were developed and validated ...

  • A Summary of Available Analytical Methods for the Determination of Siloxanes in Biogas

    ABSTRACT The importance of measuring siloxanes has increased with the recent growth of the landfill-gas-to-energy (LFGTE) market. Siloxanes and other biogas impurities can form a residue upon combustion in engines that may increase maintenance and reduce engine lifetime.  A siloxanes analysis can assist with either determining if a bioaas purification system is needed, or if a system is ...

  • Optimized data handling for automatically calculating the Hydrocarbon Index (HI) of “Produced Waters” from gas chromatographic analysis with Galaxie™ Software

    The extraction of Oil and Gas from Subsea wells produces large quantities of waste water contaminated with hydrocarbons. These “Produced Waters” are disposed of directly into the oceans. Determination of the Hydrocarbon Index (HI) is required to meet environmental legislation.Traditionally infra red methods have been used but these require solvents extraction using solvents that present their own ...


  • Case study - EDRO in soil at petroleum tank farm site

    Environmental engineers needed quick and accurate screening analysis on a tank farm contaminated with a subsurface plume of fuel oil. Sitelab's EDRO test was performed to delineate the vertical extent of contamination. A drill rig was used to collect samples from the surface down to twenty feet at different locations throughout the property. They needed to quantify the size of the NAPL plume in ...

  • Case study - EDRO in soil at wharf remediation site

    Sitelab Calibration Kit CAL-042 is used for EDRO analysis. The UVF-3100 detects hydrocarbons in the C10-C36 range. A Licensed Site Professional (LSP) used Sitelab to investigate a commercial waterfront property, contaminated with a plume of LNAPL resulting from fuel tanks which once stored heating oil, diesel and gasoline dating back to the 1950s. The site is in Massachusetts, where laboratories ...

  • Case study - Canada crude oil sites

    The Canadian Council of Ministers of the Environment requires laboratories to use the CCME’s Petroleum Hydrocarbon (PHC) Method, where GC-FID instrumentation is used to report VPH and EPH hydrocarbon fractions. Sitelab’s popular Extended Diesel Range Organics (EDRO) test typically detects hydrocarbons in the C10 to C36 carbon range, but the UVF will pick up heavier compounds up to ...

  • Case study - EPH in soil with No. 6 fuel oil

    No. 6 fuel oils (heavy fuel oil, bunker C oil) is often used in industry for heat, steam or power generation. A consultant used Sitelab to investigate two different spill sites contaminated with subsurface plumes of NAPL resulting from leaking underground storage tanks (USTs). Soils were collected from borings using a drill rig and field screened for their EPH aromatic content. Split samples ...
