... chromatography to fingerprint crude oil. Fingerprints can then be used to determine the source oil for an oil formation. Therefore, each crude oil has a unique fingerprint that can potentially be determined using ... GC-TOFMS) was used to analyze petroleum biomarkers creating unique fingerprints of crude oil samples and tarballs collected after the Deepwater Horizon oil spill. ...
ChromaBLOGraphy: Dilution and cleanup strategies for QuEChERS extracts of food prior to LC-MS/MS… and Tarballs!
If you missed the newly published tour de force piece from Julie Kowalski, check it out here: ”Mitigating Matrix Effects: Examination of Dilution, QuEChERS, and Calibration Strategies for LC-MS/MS Analysis of Pesticide Residues in Diverse Food Types.” Same thing for another excellent article just published by Michelle Misselwitz, “Fingerprinting Crude Oils and Tarballs using Biomarkers and Comprehensive Two-Dimensional Gas Chromatography.” [...]
ChromaBLOGraphy: This isn’t your average CSI, the International Network of Environmental Forensics (INEF)
Next week (June 10-12) at the Pennsylvania State University (PSU) the International Network of Environmental Forensics conference is being held. This isn’t your typical crime scene investigation but, as defined by the INEF, “environmental forensics is the use of scientific techniques to identify the source, age, and timing of a contaminant into the environment.” We [...]
YOUR GUIDE FOR Environmental Sampling and Analysis
The year 1936 marks the beginning of organic geochemistry. It started with Alfred Treibs’ discovery of porphyrins in petroleum; compounds that closely resemble chlorophylls in plant matter. Another 25 years would pass before scientists recognized that these compounds, known as biomarkers, could reveal insights into the evolution of plants and animals spanning a time frame […]
As in years past, Restek sent a contingent of environmental and air chromatography experts to the National Environmental Monitoring Conference (NEMC). This year’s event took place in Washington, DC, and featured talks from our own Michelle Misselwitz, Jason Herrington, and … Continue reading
