Multiresidue Analysis of 100 pesticides in Food Samples by LC/Triple Quadrupole Mass Spectrometry
Imma Ferrer and E. Michael Thurman, Pesticide Residue Research Group, University of Almeria; Yanyan Fang, Paul Zavitsanos, and Jerry A. Zweigenbaum, Agilent Technologies, Inc.
A method for confirming a group of 100 pesticides in vegetable and fruit samples was developed using the Agilent G6410AA Triple Quadrupole MS. The sensitivity obtained meets the maximum residue levels (MRLs) established by the European Union regulation. The analytical performance of the method was evaluated for different types of fruit and vegetables — orange, tomato, and green pepper — showing little or no matrix effects. A ZORBAX Eclipse XDB C8 column was used, and Agilent QuEChERS was used for sample preparation. |

Multiresidue Analysis of 301 Pesticides in Food Samples by LC/Triple Quadrupole Mass Spectrometry
E. Michael Thurman and Imma Ferrer, Department of Civil, Environmental and Architectural Engineering Center for Environmental Mass Spectrometry, University of Colorado; and Jerry A. Zweigenbaum, Agilent Technologies, Inc.
An analytical methodology for screening and confirming the presence of 301 pesticides in vegetable samples was developed using the Agilent G6410A Triple Quadrupole mass spectrometer (QQQ). We found that 90% could be identified using this procedure with a limit of detection (LOD) in vegetable matrices of 0.01 mg/kg (ppm) or below. A ZORBAX Eclipse Plus RRHT SB-C18 column was used. |

Analysis of Color Additives in Sweets
Siji Joseph, Agilent Technologies, Inc.
A robust HPLC method for simultaneous determination of 10 synthetic colorants is discussed in detail. Separation and quantification were achieved with an Agilent 1260 Infinity LC System using an Agilent Poroshell EC-C18 column. The HPLC method was effectively transferred to a short UHPLC method using an Agilent 1290 Infinity LC System for faster analysis without compromising resolution. |

Analysis of Bisphenol A Leaching from Baby Feeding Bottles
Syed Salman Lateef, Agilent Technologies, Inc.
Bisphenol A can leach out from the plastic surfaces of food containers and has been detected in various matrices such as plasma, urine, and groundwater. We describe a method to quantify bisphenol A and a structurally similar analog bisphenol F extracted from baby feeding bottles. The method was developed on an Agilent 1260 Infinity LC system using an Agilent ZORBAX Eclipse Plus C18 column. |
