Meet stringent detection limits of regulated compounds with a known and needed level of confidence using ultratrace analysis from SGS.
The trend in environmental legislation and regulation has been increasingly driven by attempts to measure exposure and associated health effects in the population via risk assessments. For these studies to have meaning, it is necessary to detect hazardous compounds at significantly lower levels. In the area of dioxins/furans, coplanar PCBs, polynuclear aromatics and pesticides, the necessary detection levels have resulted in the need for superior detectors, fit-for-purpose technology and effective quality control. Ultratrace analysis based on true isotope dilution, using high-resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC-HRMS) has become the preferred analytical technique.
Why choose our ultratrace analysis service?
Our analytical services and advanced technologies:
- Apply fit-for-purpose procedures and controls that continually improve and adapt laboratory performance to generate effective data. Our comprehensive approach also determines the analyte- (as well as TEQ) and sample-specific combined standard uncertainty to demonstrate data quality, and to aid sampling and experiment design
- Process PCDD/F congener profiles using our dfa technology for quality control purposes, and shed light onto the mechanisms of formation, helping our clients identify causes of deviations from normal operation (exceedance of regulated action/emission levels)
- Target and report all 136 PCDD/F tetra- through octa-chlorinated congeners by name, and with appropriate controls to ensure distortion-free isomer profiles
- Exceed existing methods requirements by using true isotope-dilution mass spectrometry for all TEF-target analytes, providing the most accurate TEQ determination
- Identify unknown compounds using high-resolution analysis with library searching and/or exact mass measurement with elemental composition determination
Our ultratrace services offer:
- Analysis of dioxins/furans, PCBs, PAHs, SVOAs and pesticides using EPA Methods 23, 8290, 1613, 1668, 1699, 0023A, TO-9A, CARB 428, 429, and their international equivalents/derivatives; WHO-2 (combined D/F+PCB analysis, e.g. for EU food/feed testing)
- Instrumentation includes eight high-resolution, magnetic-sector, double-focusing mass spectrometers
- Project specific method development and consulting unsurpassed in the industry
- Certifications including NELAC, US States, and USDA international soil permit
- Turnaround times up to our ultra-rapid 55-hour D/F analysis
- A quality assurance program compliant with good laboratory practice standards (GLP), FIFRA/TSCA GLPs, and laboratory quality control samples that meet/exceed method criteria
- Data reports that include high resolution, indexed PDFs with full-color chromatograms, plus our unique performance-based criteria analysis (PBCA). Chromatographic data may be reviewed interactively using our proprietary UTP software
- Online reporting of data from SGS Engage, an encrypted and password protected website
