| Abstract: | Objective To establish a rapid and accurate method for Simultaneous qualitative and quantitative analysis of common poisons. Methods 57 kinds of common toxicants were analyzed by GC/MS. Results A user＇s library of QED spectrum of 57 kinds of toxicants was obtained and the parameters of selected reaction monitoring were optimized. Conclusion This meth- od is rapid, sensitive and accurate. With this method, the qualitative and quantitative testing can be completed in a single scan. |
