An analytical procedure for morphine-3-glucuronide (M3G) and morphine (M) in the human urine was investigated by using high-performance liquid chromatography coupled with atomospheric pressure ionization mass spectrometry (LC/APCI-MS). The samples were purified with Sep-Pak C_<18> cartridges. The LC separation was carried out using a L-column ODS in 50 mM ammonium acetate-methanol (86 : 14 v/v). The calibration graphs constructed by the absolute calibration curve method showed linearity over the concentration range of 30 to 1000 ng/ml (γ=0.9965) for M3G and 30 to 2000 ng/ml (γ=0.9970) for M. The detection limits by selected ion monitoring (SIM) were 3 ng/ml for M3G and 1 ng/ml for M, and by scan mode were 350 ng/ml for M3G and 80 ng/ml for M. The coefficients of variations for M3G and M were 4.79 and 3.15% at 1 μg/ml, respectively.
