Identification and semi-quantitation of dextromethorphan and its metabolite in urine using the REMEDi HS system

To determinate dextromethorphan (DMP) and its active metabolite dextrorphan (DRP) in urine was performed using $REMEDi^TM$ (Rapid EMErgency Drug identification) that is a fully automated multicolumn high performance liquid chromatographic (HPLC) system with a scanning ultraviolet detector. The limits of detection for DMP and DRP were 0.10 and 0.15 $\mu$g/mL, respectively. The standard curves were linear, with correlation coefficients (r ＞ 0.975) in the concentration range of 0.5~10.0 $\mu$g/mL. (omitted)
