Thermo Fisher Scientific (Waltham, Massachusetts) announced that it has received a Ringer Technology Innovation Award for helping Chinese laboratories develop melamine detection methods following the discovery of tainted milk and infant formula in China. Ringer Trade Publishing presented the award. Thermo Fisher Scientific’s melamine testing approach comprises sample preparation, instrumentation, consumables, and a method based on a tandem liquid chromatography–mass spectrometry system. China’s General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) used the method as a reference to create their own method. Melamine, an inexpensive chemical used in plastics manufacturing, and cyanuric acid, a melamine by-product, were found in milk-based products and food additives. When added to milk products, melamine increases the perceived protein content. Chinese officials in 2008 linked several deaths to melamine contamination, which led the U.S. FDA to issue an alert focused on milk-based products from China.
Inside the Laboratory: The Gionfriddo Group at the University of Buffalo
March 28th 2024In this edition of “Inside the Laboratory,” Emanuela Gionfriddo, PhD, an associate professor of chemistry at the University at Buffalo, discusses her group’s current research endeavors, including using solid-phase microextraction (SPME) coupled to liquid chromatography (LC) and gas chromatography (GC) to further understand the chemical relationship between environmental exposure and disease and elucidate micropollutants fate in the environment and biological systems.
Transferring Methods to Compact and Portable HPLC
February 14th 2024The current trend in laboratory equipment design is the miniaturization of laboratory instruments. Smaller-scale HPLC instruments offer benefits that cannot be matched by analytical-scale equipment, especially in the areas of portability, reduced fluid volumes, and reduced operating costs. Yet, the miniaturization of laboratory equipment has brought with it a unique set of challenges, including transferring methods to compact LC. Capillary LC expands the use of LC to applications not currently done using conventional LC in a wide array of application areas, including pharmaceutical, food and beverage, petrochemical, environmental, and oil and gas. Greg Ward, Axcend’s CEO wrote, “Customers want an HPLC system with a small footprint, low flow rates and green chemistry.” Join his podcast where he shares method transfer in these application areas.
Sustainable Green Solvents in Microextraction: A Review of Recent Advancements
