Metrohm AG (Herisau, Switzerland) has released a method for the determination of melamine in milk powder and other food using ion chromatography after in-line sample dialysis.
Metrohm AG (Herisau, Switzerland) has released a method for the determination of melamine in milk powder and other food using ion chromatography after in-line sample dialysis. The method reportedly is sensitive enough to quantify melamine contents below the limit set by food safety regulatory agencies around the world. The method involves the use of the company’s model 844 UV/VIS Compact IC system, which is designed for the spectrophotometric determination of polar substances, anions, and cations.
Inside the Laboratory: The Gionfriddo Group at the University at 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.
