Abstract: A GC/ECD method was established to determine triazolam in human urine qualitatively and quantitatively. The triazolam was extracted from 2ml urine with 2 x 2ml chloroform.The retention time of triazolam was 10. 74 min. The limit ofthe determination was 0. 5ng/ml. The recovery of the procedure in 5 ng/ml was 95.98%, CV = 7. 85% (n = 5). Thelimit of quantitation is 2 - 50ng/ml.

Key words: triazolam, GC/ECD, urine
