Persistent organic pollutants (POPs) are environmental contaminants characterized by their persistence, long-range transport and biomagnification in food chains and bioaccumulation in humans. Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzo-furans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) are commonly known as dioxins and furans and internationally recognized and the most important toxic members of POPs. The detection and confirmation of dioxins requires a high level of analytical performance.

Until recently, EU legislation required the use of HRMS based on magnetic sector analyzers as a standard approach for confirmatory analysis of dioxins in feed and food. However, recent technological advances in GC-MS/MS instruments have enabled other alternatives (Commission Regulation (EU) No 589, 2014 and Commission Regulation (EU) No 709, 2014). These analytical techniques achieve the required sensitivity and selectivity for dioxin analysis. As result, GC-MS/MS is now permitted for use in the EU to control the maximum levels for dioxins in food and feed as a full confirmatory method. When using GC-MS/MS, specific performance criteria for dioxin confirmation must be met in addition to the criteria described by the European Commission regulations.

In this presentation, the results of several experiments performed using triple quadrupole for dioxin analysis in food and feed samples is displayed. In addition, other GC- MS approaches which in the near future could be also suitable to be considered for same purposes will be noticed.

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. Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.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 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 TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.DioxinsDioxins are a group of persistent environmental pollutants (POPs) that comprise of chlorinated organic chemicals. These airborne particles can deposit on plants or in water, and animals can accumulate these highly toxic molecules in their fat.Chemical Residues in FoodPersistent Organic PollutantsPolychlorinated Biphenyls
