Abstract:

This article introduces the selection principles,mechanisms of action,development trends,and application examples of isotope internal standards in biological sample detection. It elucidates the important role of this method in improving the sensitivity,accuracy,eliminating and reducing the loss of analyte and matrix interference caused by sample pretreatment. This article reviews the current application status of isotope dilution mass spectrometry in food safety,environmental health and biomedicine,and lists the detection examples of this method in different types of complex biological materials such as serum,whole blood and urine. It fully demonstrates the important role that this method will play in the detection of biomaterial chemicals in the future,providing data and technical support for the monitoring of human biological samples in China.

Key words: Isotope internal standard, Biological samples, Chemical detection, Effect
