| Abstract: | Without any sample pretreatment,nano surface desorption atmospheric pressure chemical ionization mass spectrometry（SDAPCI-MS） directly detected trace amounts of cocaine in the spiked Mashed Potato（produced by KFC） samples.The results demonstrated that,based on SDAPCI-MS,the trace amounts of cocaine in Mashed Potato could be direct detected by tacking trace samples（ng）,and the operation was simple and easy for direct detection of low-level cocaine.Promisingly,this technique can be used for the rapid determination of trace analytes in viscous complex matrix. |
