Internal Standard for Food

Food safety issues have become a global topic, and vicious food safety incidents continue to occur internationally, causing huge economic losses. Food safety testing has now become one of the hot topics of concern in various countries. Currently, the most advanced method for food safety testing in the world is isotope dilution mass spectrometry. This method uses stable isotope-labeled compounds (13C, 15N, 2H, etc.) which with the same molecular structure as the analytes as internal standards. Through quantitative mold detection with high-end instruments such as LC-MS and LC-MS/MS, the content of harmful substances in food can be accurately quantified to ensure the safety of food on the market[1].
