Environmental pollutants in foods and beverages—such as persistent organic pollutants, also known as POPs—are of great interest when it comes to food safety. Dioxins, polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) are among the most common.
Using state-of-the-art systems, we provide solutions for some of the most challenging food safety and environmental pollutant determinations.
Resistant to environmental degradation, persistent organic pollutants mainly accumulate through bio-accumulation within fatty deposits in meat, fish, eggs or other dairy products. They can have significant effects on humans and animals as they migrate through the food chain.
Dioxins in food, such as polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs), constitute a group of highly toxic organic compounds formed unintentionally, mainly in waste combustion processes or as by-products of industrial manufacturing of certain chemicals, such as chlorinated pesticides.
Continual changes in POPs research and regulatory requirements drive the need for ever-lower limits of detection and quantitation, for both known and unknown compounds. View the on-demand POPs symposium recent developments in POPs analysis .
To reinforce our commitment, we have established a Persistent Organic Pollutants (POPs) Center of Excellence, staffed with experts in POPs analysis, to be used as a direct resource for our customers and associates. Located in Bremen, Germany, the center supports our customers and associates internationally.
We provide a wide array of solutions to meet the regulatory requirements of POPs analysis. Open the sections below to learn more about instrumentation for these important analyses.
Extract organic pollutants from solid and semisolid samples prior to POPs analysis by using Dionex ASE 350 and ASE 150 solvent extractor systems. The system uses elevated temperature and pressure with organic and aqueous solvents to increase the efficiency of the extraction process.
The use of the novel water-absorbing polymer of the Dionex ASE Prep MAP expands the capabilities of the accelerated solvent extraction technique and allows for the extraction of analytes from samples containing up 85% water.
Concentration and evaporation is an important step in achieving accurate analytical results with sample extracts. The Thermo Scientific Rocket Evaporator automates this process and can be used either to dry samples completely or to concentrate them directly into autosampler vials. This system can process large volumes of solvent extract (up to 450 mL) and also allows direct transfer of 60 mL extract from the accelerated solvent extraction system to eliminate manual sample transfer steps during the POPs testing process.
Our broad range of high-quality chromatography columns and consumables is designed to ensure that analytical systems operate at peak performance, providing optimal sample assessment regardless of matrix type.
Thermo Scientific TraceGOLD GC columns provide excellent quality and performance and Thermo Scientific LC and LC-MS columns and consumables are designed to meet the challenging requirements of POPs analysis.
