Abstract: |
Time-of-flight mass spectrometry(TOF-MS) is a new mass spectrometric technology,with the advantages of wide mass range,high sensitivity,high resolution,accurate mass analysis and high analysis speed.This artical introduces the basic principles and performance characteristics of TOF-MS,and summarizes the application progress of TOF-MS in the high-throughput screening and confirmatory analysis of food contaminants and their metabolites. |
