Abstract
A specific and sensitive rapid high-pedormance liquid chromatographic method has been developed for determination of thiocyanate (SCN-) in plasma. This method is based on anion exchange chromatography after a simple ultrafiltration of plasma diluted in water. The detection of SCN- is carried out in ultraviolet (λ = 210 nm). The proposed method is linear in the range 1–30 mg/L. Intra-assay and interassay accuracy and precision were maintained within the designated limit (< 20%). The total recovery of SCN- varied between 97 and 103.9%. The method described should be useful for clinical medicine. Moreover, this method was applied to the analysis of SCN- plasma in deceased subjects, within the context of fire, and could be of interest in forensic science as a useful additional measurement tool for cyanide determination in blood.
