Characterization of Triacylglycerides (TAGs) in Vegetable Oils using MALDI LTQ Orbitrap XL InstrumentationInstrument Type: Unspecified
The world’s population growth has led to increase in consumption of vegetable oils by 4.5% in 2011. By 2020, the annual production is expected to expand by 23%. Import rates for vegetable oils into the EU are predicted to rise significantly. Cases of economic adulteration of vegetable oils with non-authentic and less expensive oil adjuncts occur frequently. We describe a method to uncover structures of specific TAGs and TAG distribution patterns among various vegetable oils exploiting full MS and CID-based MSn experiments using the Thermo Scientific MALDI LTQ Orbitrap XL.
Simultaneous Determination of Oil Dispersants in Seawater and Crude Oil by LC and Tandem MSInstrument Type: LCMSMS
On April 20, 2010 the Deepwater Horizon (MC-252) oil platform caught fire and sank in the Gulf of Mexico, creating a large release of oil and gas from the riser pipe and uncapped well head. Containment efforts included heavy use of oil dispersants Corexit EC9500A and Corexit EC9527A which were approved for use in the Gulf of Mexico oil spill by the U.S. EPA. Tracking Corexit in the environment is a priority due to its low-to-moderate toxicity. We describe an analytical method capable of detecting its presence in seawater even when large dilution factors are expected.
Determination of Chloride in Algal Oil Using Combustion Ion ChromatographyInstrument Type: IC
Oil extracted from fish and algae is a renewable alternative to petroleum-based sources. If this oil is used as a lubricant, chloride needs to be monitored and its level minimized to reduce the likelihood that corrosive HCl will form. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-2100 ion chromatograph, the concentration of chloride can be determined accurately and quickly.
Enhanced resolution of polyunsaturated lipids in a nutritional supplement by HPLC-CADInstrument Type: HPLC-CAD
The Thermo Scientific UltiMate 3000 HPLC system is applied for the analysis of polyunsaturated lipids in a nutritional supplement. The separation is performed on a Thermo Scientific Accucore C30 HPLC column, with charged aerosol detection (CAD).
Improved determination of antioxidants in edible oils by AOAC 983.15 using a Thermo Scientific Acclaim 120 C18 HPLC columnInstrument Type: HPLC
The Thermo Scientific Acclaim 120 C18 column is used for the analysis of synthetic antioxidants in edible oils, with a diode array detector for confirmation.
