[eBook] Routine or Research: GC-Orbitrap for Food Safety Analysis

Ensuring the safety of the world’s food supply is critical, but there are concerns about the safety of global food supply chains because food can be grown and processed in widely differing environments under a variety of regulatory frameworks. At any point in the process, products may become contaminated and unfit for consumption. Whether you are ensuring regulatory compliance or involved in product development you will face the demand for ever changing regulations, increasing the scope of analysis and needing to be right first time. These challenges call for sophisticated analytical techniques such as Orbitrap-based high-resolution mass spectrometry that provides distinct advantages.

Thermo_eBook_Food_HeaderIn this new eBook we bring together some of the key application notes written in collaboration with scientists from around the world that demonstrate how GC-Orbitrap™ makes a real difference to food safety.
