Abstract
Interest in facile and sensitive methods for cyanide detection is related to the extreme cyanide toxicity and its importance in forensic toxicology. In this research a novel application of Ion Mobility Spectrometry (IMS) was demonstrated for rapid determination of cyanide poisoning in postmortem toxicology. In addition, a simple method for the sample preparation was applied based on the analyte (cyanide anion) transfer as HCN to the headspace and direct injection to IMS. The method showed a linear dynamic range of 50–2000 µg/L with R2 > 0.99, a high sensitivity (LOD of 20.4 µg/L and LOQ of 68.1 µg/L). Good repeatability (intra- and inter-assays, CV < 15 %) and excellent extraction recovery (82 -94 %) were obtained. After validation, the method was applied in the analysis of postmortem human blood samples in forensic cases. In all samples, the cyanide was promptly quantified.
