Bruker Daltonics (Billerica, Massachusetts) has released a method for the detection and quantification of melamine and cyanuric acid that can be used by food safety laboratories. The 5-min method is based on liquid chromatography (LC) with tandem mass spectrometry (MS) detection. The method uses the company’s HCTultra high-capacity ion-trap MS system hyphenated with a Dionex (Sunnyvale, California) UltiMate 3000 LC system and an Acclaim Mixed-Mode WAX-1 column. According to the company, the method is able to detect melamine in various matrixes at concentrations well below those required by food safety and other regulatory authorities around the world. The US FDA’s limits are 1 ppm for melamine and cyanuric acid in infant formula and 2.5 ppm for other foods.
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.
