| Abstract: | Law enforcement personnel interdicted an illegal shipment of a chemical suspected to be an illicit drug. However, literature within the package indicated that the substance was actually tetrodotoxin, a potent marine neurotoxin. Analyses of the questioned samples by gas chromatography–mass spectrometry revealed no evidence for the presence of illicit drugs, but this technique was ineffectual for the identification of tetrodotoxin. Direct-inlet-probe mass spectrometry was likewise unable to characterize the chemical identity of the subject material. Electrospray-ionization mass spectrometry was implemented to successfully identify the interdicted substance as tetrodotoxin. |
