Abstract |
|
内容記述 |
A rapid and sensitive electrospray ionization tandem mass spectrometric (ESI-MS-MS) procedure was developed for the determination of cyanide (CN-). CN- in biological fluids was reacted with NaAuCl4 to produce dicyanogold, Au(CN)2- which was extracted with methyl isobutyl ketone (MIBK). One μL of the extract was injected directly into an ESI-MS-MS instrument. Quantification of CN-was performed by selected reaction monitoring of the product ion CN- at m/z 26 that derived from precursor ion Au(CN)2- at m/z 249. CN- could be measured in the quantification range of 10-7 to 5×10-5 M with the limit of detection at 4×10-8 M using 10 μL of urine within 10 min. A victim’s urine and gastric content were diluted with water to 4-fold and 500-fold and measured, respectively. |
