- Abstract
Objective To establish a GC/MS/MS derivatization method for determining the cyanide in blood. Methods Blood sample was sequentially added with the solutions of aniline cyclohexane, sodium nitrite and hydrochloric acid, then being subjected to vortex for mixing. After one more addition of copper sulfate solution into the above sampling blood, the mixture was heated at 50°C for 15 min, thus resulting in the benzyl cyanide/chloride to be determined by GC/MS/MS, with the ions m/z 76 and m/z 65 for quantitative analysis of characteristic peak from benzyl cyanide/chloride. Results The cyanide ions in blood sample showed the limit of detection as 0.05 μg/mL and the average recovery about 95%. Conclusion This method is of specificity, rapid for qualitative analysis of cyanide in blood.
