A capillary electrophoretic method for a high-sensitivity analysis of cyanide has been developed. Cyanide was derivatized with 2,3-naphthalenedialdehyde and taurine to give a fluorescent product of 1-cyanobenz[f]isoindole. This compound was detected with high sensitivity by fluorescence detection. The detection limit was 0.1 ng/mL, and the calibration curve was linear over the range 0.1 - 200 ng/mL. The precision of the migration time of within-run assays (n = 6) of 1 ng/mL cyanide standard solution was 0.14%. The precision of the peak area for the same runs was 1.0%. This method was applicable to blood analysis. Detection of the cyanide derivative by UV was also examined.
