  • US EPA Method 8270 Semivolatiles on the Equity-5

    US EPA Method 8270 describes the analysis of a wide variety of semivolatile compounds by GC/MS. In this application, the Equity-5 was used to analyze 74 compounds commonly targeted for analysis by environmental laboratories. The analysis also included 6 internal standards and 8 surrogates. The Equity column showed excellent peak shape and response for both basic and acidic compounds, including ...

  • Fast GC-MS Analysis of US EPA Method 8270D Semivolatiles Using Supelco SLB-5ms

    US EPA Method 8270D specifies a procedure for the determination of semivolatiles in solid waste and ground water samples. The method specifies that all analyses must be completed within 12 hours of meeting specific MS tune criteria. In this application, the principles of fast GC were applied to analyze a typical 8270 analyte list in under 8.5 minutes. This was achieved by using a 20 m x 0.18 ...

  • Use of SDI carcinogenic PAHs RaPID assay kits for semi-quantitative screening consistent with SW-846 method 4035

    BACKGROUND The Methods Section of the EPA Office of Solid Waste (OSW) has stated a need for more rapid, less expensive field screening procedures that do not compromise the accuracy of contaminant evaluation. The OSW screening approach incorporates a single point threshold or multiple individual point discriminators giving results in semiquantitative ranges lying between these points. SDI ...


  • 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 ...

  • Case study - Performance testing PAHs in asphalt in France

    ESITC – France: New regulations across Europe are requiring laboratory analysis for PAH content in asphalt. Researchers at ESITC’s lab are using the Sitelab TD-500D analyzer to monitor PAH levels in new, reclaimed and recycled asphalt. Maximum PAH limit for reuse is 50 ppm. In this study, three asphalt samples were ground down to different particle sizes and sent to four certified ...

  • Use of PAHs RaPID ASSAY kits for semi-quantitative screening consistent with SW-846 Methood 4035

    BACKGROUND The Methods Section of the EPA Office of Solid Waste (OSW) has stated a need for more rapid, less expensive field screening procedures that do not compromise the accuracy of contaminant evaluation. The OSW screening approach incorporates a single point threshold or multiple individual point discriminators giving results in semiquantitative ranges lying between these points. SDI ...


  • Case study - Performance testing PAHs in soil

    These case studies highlight Sitelab’s accuracy from customers who have used the UVF-3100D for testing Target PAHs. This test correlates well to U.S. EPA Method 8270 or similar GC methods, which includes a list of 16 or more compounds. The analyzer is fitted with special optical filters sensitive to this same group of hydrocarbons. Examples of UVF-3100D testing Polycyclic Aromatic ...

  • Large Volume Splitless Injection Using an Unmodified Split/Splitless Inlet and GC-TOFMS for Pesticides and Brominated Flame Retardants

    Abstract Large volume splitless injection for gas chromatography typically requires a special injection port, for example, a programmable temperature vaporizer (PTV), but an alternative setup using concurrent solvent recondensation–large volume splitless injection (CSR-LVSI) and a split/splitless injection port has been reported. This technique was used here, both with and without ...
