Analyzing Multi-Class Persistent Organic Pollutants (OCPs, PCBs, PBDEs, and PAHs) in Food Matrices in a Single Injection by APGC-MS/MS

Waters
24 Sept 2014

This application note describes the development and validation of a quantitative method for 141 multi-class POP compounds in a variety of foodstuffs to ensure continued monitoring and consumer safety in Quebec, Canada. The sensitivity, selectivity, and quantification capability of APGC, when coupled with the Waters® Xevo TQ-S is determined, using a generic sample preparation method for the satisfactory extraction of all analytes from a variety of food matrices.

MassLynx MS Software

Waters

Acquire, Analyze, Manage, and Share Mass Spectrometry Information MassLynx™ Software increases the speed at which you can convert your sample data into valuable knowledge. It provides you with the fundamental platform to acquire, analyze, manage, and share your mass spectrometry information. MassLynx intelligently controls any Waters mass spectrometry system, from sample and solvent management components to mass spectrometer and auxiliary detectors. MassLynx Software may acquire nominal mass, exact mass, MS/MS and exact mass MS/MS data. MassLynx’s Sample List is the core of the system. It maintains and consolidates the data on all of your samples. You also initiate any activities related to your sample from the Sample List. This "sample centric" approach simplifies the interaction with your LC/MS or GC/MS system, acquired data and processed results. Process Application-specific Data MassLynx Software features general purpose and specialized Application Managers that provide information for your specific MS analyses and data. Two come standard with MassLynx: QuanLynx™ for automated quantification included as standard with MassLynx OpenLynx™ for qualitative screening and identification Optional Application Managers can perform: Targeted quantitative analysis Mass-directed purification Metabolite identification Deconvolution of complex chromatograms Metabonomics & metabolomics Protein identification and protein characterization

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Food FraudFood adulteration refers to food when it has been has been altered unlawfully with the addition of another lower commodity food product to increase quantity. The 2013 European horsemeat scandal saw the adulteration of beef products with the addition of horse meat.Food ContaminationFood contamination refers to the presence of harmful substances or pathogens in food, posing risks to human health. Contaminants can be biological, chemical, or physical, and their detection is crucial for ensuring food safety. Advanced testing methods like PCR, chromatography, and spectroscopy are used to identify contaminants in food products. Browse our peer-reviewed product directory to find the best solutions for food contamination detection, compare products, check reviews, and get pricing directly from manufacturers.
