TDI-Brooks International, Inc. offers a comprehensive suite of geotechnical analytical services for characterizing offshore geotechnical samples. All of our services are offered in the onshore laboratory. Some of the services are also offered in conjunction with our offshore geotechnical programs.
Total Scanning Fluorescence (TSF) is a semi-quantitative analytical technique that is selectively sensitive to aromatic compounds and, as such, is a valuable tool for detecting the presence of petroleum related hydrocarbons in sediment extracts. Increasing TSF intensity (expressed in arbitrary intensity units) generally corresponds to increasing aromatic hydrocarbon concentrations in sediment extracts.
Not all laboratories can offer the services you require. We can facilitate extended services by partnering with other labs in order to provide you with a sole source solution to your analytical needs. Please contact us for more information.
We have a highly trained staff with a broad range of experience in environmental analytical techniques. If you require services not listed here, please for more information
Employing the Lloyd Kahn procedure, we routinely analyze percent total carbon, percent organic carbon and percent inorganic carbon using the LECO corporation model 632 carbon analyzer in sediments and soils using direct combustion/infrared detection. In addition to the determination of solids for percent carbon, we can provide % carbon results for both fresh and marine water samples using the OI Analytical model 700 or 1010 Wet Oxidation Total Organic Carbon Analyzers.
Established in 1996, TDI Brooks provides high-quality analytical services and scientific interpretation with a focus on petroleum geochemistry, surface geochemical exploration, oil spill response, environmental chemistry, and environmental assessments via our laboratory affiliate, B&B Laboratories. We have established a highly technical, state-of-the-art laboratory facility in College Station, Texas, and now direct an accomplished, motivated, and competent staff with a broad range of published expertise in geochemical and environmental chemistry as well as in biological, geological and physical oceanography.
From determining trace contaminants in sediment, soils, tissue, and water to oil spill response, we have extensive experience with programs such as NOAA’s Status and Trends Mussel Watch (1999-currently), United States Fish and Wildlife Analytical Control Facility (2002-currently), and our involvement in oil spill response as with Mississippi Canyon 252 (Deepwater Horizon) Natural Resource Damage Assessment (2010-currently).
As part of our long standing involvement with NOAA and USFWS, TDI-Brooks routinely analyze an extensive congener specific list of PCBs and Chlorinated Pesticides from Chlordanes, DDTs, and isomers of Hexachlorohexanes to name a few. High quality Chlorinated Pesticide and Polychlorinated biphenyl (PCB) dtermination is performed using high resolution gas chromatography / electron capture detection (GC/ECD) and is a quantitative analytical technique used for the determination of chlorinated hydrocarbons in extracts of tissue, water, and sediment. Method Detection Limits using this technique are very low (
