May 2012 Subscribe Go to Application Note Library Comprehensive Pesticide Analysis in Juice Using a Combination of GC–MS and LC–MS Methods Fadwa Al-Taher, Agilent Technologies Methods have been developed on Agilent GC–MS and LC–MS instrument platforms that reliably detect and quantitate 39 pesticides in a vegetable juice matrix.   Analysis of Phytoestrogens in Soy Milk by GC–MS-MS with the Agilent 7000 Series Triple Quadrupole GC–MS Imma Ferrer, Agilent Technologies An analytical method for the identification of eight plant phytoestrogens (biochanin A, coumestrol, daidzein, equol, formononetin, glycitein, genistein, and prunetin) in soy milk was developed using gas chromatography tandem mass spectrometry (GC–MS-MS).   Simple Rapid Analysis of Trace Metals in Foods Using the Agilent 7700x ICP-MS Steve Wilbur, Agilent Technologies The Agilent 7700x ICP-MS is capable of accurately analyzing a variety of foods for metals at trace and major levels using a single collision cell method.   Determination of Aflatoxins in Food by LC–MS-MS Masahiko Takino, Agilent Technologies A sensitive and selective analytical method for the determination of aflatoxin G1, G2, B1, and B2 residues in cereals using the Agilent G6410AA LC–MS Triple Quadrupole Mass Spectrometer was developed. EPA Method 538 Determination of Selected Organic Contaminants in Drinking Water by Direct Aqueous Injection Imma Ferrer, Agilent Technologies A new method from the U.S. EPA (538) on 11 selected organic contaminants in drinking water by direct aqueous injection using UHPLC and the Agilent Model 6460 Triple Quadrupole LC–MS system.   Sensitive Detection of Pyrethroids in Surface Water and Sediment Stephan Baumann, Agilent Technologies A method has been developed on the 7000 series Triple Quadrupole GC–MS using NCI GC–MS-MS with backflushing. It delivers estimated method detection limits for pyrethroids as low as 0.05 ppt in water samples and 0.02 ppb for sediment. Synthetic Cannabinoids in Oral Fluid Cynthia Coulter, Agilent Technologies In 2011, five members of the “synthetic cannabinoids” group or “Spice” compounds were banned in the US. This note shows the simultaneous determination of these "spice" compounds in oral fluids.   Long Term Detection of Anabolic Steroid Metabolites in Urine Stephan Baumann, Agilent Technologies A method for the long term detection of anabolic steroid metabolites in urine was developed using both the Agilent 6890N/5795B GC–MS system and the Agilent 7000 Series Triple Quadrupole GC–MS.   Enhanced Sensitivity for Biomarker Characterization in Petroleum Using Triple Quadrupole GC–MS and Backflushing Melissa Churley, Agilent Technologies A rapid, reliable method for the routine detection and quantification of biomarkers in petroleum was developed using the 7890A/7000A Series Triple Quadrupole GC–MS with backflushing using a pressure controlled tee configuration. Trace Elemental Analysis of Trichlorosilane by Agilent 7700s ICP-MS Junichi Takahashi, Agilent Technologies Metallic impurities in trichlorosilane (TCS), an intermediate product used in the production of photovoltaic (PV) silicon, must be strictly controlled in order to produce the high purity PV silicon necessary for the manufacture of solar cells.
