June 2012 Subscribe Go to Application Note Library Cost-Effective Analysis of Major, Minor, and Trace Elements in Foodstuffs Using the 4100 MP-AES Tran Nham, Agilent Technologies This application note describes a cost-effective method for the analysis of major, minor, and trace elements in foodstuffs. Determination of Fatty Acid Methyl Esters (FAMEs) in Salmon Oil Using Automated Sample Preparation Norbert Helle, Agilent Technologies The automated derivatization of fatty acids (FAs) was performed with the Agilent 7696A Sample Prep WorkBench. Since free fatty acids show tailing in gas chromatography, transformation of fatty acids into fatty acid methyl esters (FAMEs) is widely used. Determination of Chemical Contaminants in Marine Shellfish Using the Agilent 7000 Triple Quadrupole GC–MS System Agilent Technologies A sample preparation method based on a modified QuEChERS extraction has been developed along with a GC–MS-MS method for the determination of selected organo-chlorine pesticides, polyaromatic hydrocarbons, and polychlorinated biphenyl congeners.   Detection, Confirmation, and Quantification of Chloramphenicol in Honey, Shrimp and Chicken Using the 6410 LCMS Yanyan Fang, Agilent Technologies This method was developed using the G6410AA Triple Quadrupole. The sensitivity obtained exceeds the minimum required performance level (MRPL) established by the European Union regulation for food monitoring programs.   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.   Triple Quadrupole LC–MS Analysis of Aflatoxins in Various Food Samples Agilent Technologies Find out how the 6460 triple quadrupole LC–MS provides high sensitivity for carcinogenic aflatoxins with LODs well below action levels in food and feed.   Metabolomic Profiling of Wines Using LC QTOF MS and MassHunter Data Mining and Statistical Tools Lucas Vaclavik, Agilent Technologies A nontargeted metabolomic analysis approach to wine variety classification was developed using molecular feature extraction, data filtering, and statistical analysis.   Identification and Quantitation of Pesticides in Chamomile and Ginger Extracts Using an Agilent 6460 Triple Quadrupole Thomas Glauner, Agilent Technologies Triggered MRM (tMRM) analysis is applied to chamomile and ginger extracts and performed with 1290 LC and 6460 QQQ. Two examples of false positive identifications were explored: tebuthiuron in chamomile and tebufenpyrad in ginger.   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). In Situ Screening of Quality Traits in Tomato Cultivars Using the Handheld 4200 FlexScan FT-IR Spectrometer Glynda Fe G. Sayajon, Sarah Herringshaw, Alejandra M. Santos, Luis E. Rodriguez-Saona, and David M. Francis, The Ohio State University Screening of quality parameters in tomatoes has been accomplished through the use of the handheld Agilent 4200 FlexScan FT-IR spectrometer in the mid-infrared spectral region.
