Inside Front Cover: Rapid screening for 315 drugs in food and biological matrices by ultrahigh‐performance liquid chromatography quadrupole time of flight mass spectrometry and its application to a specific incident

Abstract

DOI: 10.1002/sscp.202200037 The cover picture shows the food matrix which contained some poison drugs and the biological matrices containing serum, urine and gastric juice from the people who ate the poison food that were extracted and purified by a modified QuEChERS method. The sample was acquired by ultrahigh-performance liquid chromatography quadrupole time of flight mass spectrometry and screened by self-built library. The method was validated by other three laboratories in different areas in China using different mass spectrometric techniques. The method was successfully applied to a real incident.
