A new workflow addresses the high cost and complexity faced by scientists testing food and animal feeds for low levels of dioxins and ‘dioxin-like’ polychlorinated biphenyls (dl-PCBs). The validated workflow is compliant with the latest European Union (EU) regulations aimed at controlling the maximum levels of dioxins and dl-PCBs in food and feed as a full confirmatory method.

The Thermo Scientific Dioxin Analyzer includes the Thermo Scientific Triple Quadrupole TSQ 9000 GC-MS/MS system equipped with an advanced ionization source (AEI) designed for enhanced sensitivity, and a range of productivity tools to deliver reliable and cost-effective routine analyses. The workflow includes all instrument components, capillary GC column, system suitability check, standard solutions, software and comprehensive user guidelines for rapid implementation and ongoing optimum performance. Thermo Fisher Scientific is showcasing this new workflow during the 2019 Pittsburgh Conference & Exposition (Pittcon 2019), being held March 17–21, at Booth #2632 at the Pennsylvania Conference Center, Philadelphia.

“Accurate determination of harmful contaminants like dioxins and PCBs in food and feed samples is essential for compliance and to ensure consumer safety and confidence in our food chain,” said Rajat Mehta, vice president and general manager, applied technologies, chromatography and mass spectrometry, Thermo Fisher Scientific. “The Dioxin Analyzer helps food safety scientists carry out cost-effective sensitive screening and confirmation using an ‘off-the-shelf‘ workflow that is robust, compliant and easy-to-use.”

“Food-testing laboratories analyze a range of complex samples meticulously, providing results quickly and with confidence,” said Divan Khalil, senior director, food and beverage, Thermo Fisher Scientific. “The sensitivity and robustness of the Dioxin Analyzer instrumentation permits minimal sample concentration steps, delivers good uptime and improved productivity in the laboratory.”

With the Thermo Scientific Chromeleon Chromatography Data System (CDS) software built into the workflow, the Dioxin Analyzer offers:

Sensitive determination of trace levels in complex sample matrices facilitated by the new Thermo Scientific Advanced Electron Ionization source, which permits the use of low sample weights that is expected to provide low costs of sample preparation and system maintenance.
Productive data processing and reporting through a comprehensive suite of tools and pre-loaded acquisition, calculation and reporting templates designed to meet EU requirements for PCBs/dioxin confirmation.
Operational simplicity with setup guidance documentation and quality check standard that can facilitate out-of-box implementation and help with training needs.
