For now, TLC is the generally used method for the separation and identification of opium drugs. In this report, we used both GC and HPLC to separate and identify morphine HCl, Heroin, Codeine phosphate and pentazocine. The performance is good and efficient. 3% SE-30 and ov-17, 180 cm×2 mm ID glass tubing, FID and 230℃ were applied for the GC experiment while the experimental conditions for HPLC were (1). column: μ-Bondapak C18; (2). Mobile phase: 5.8 g sodium Dioctyl-Sulfosuccinate in Methanol: Tetrahydrofuran: water=650ml: 20ml: 330ml; (3). UV detector at 280nm; (4). flow rate: 1.5ml/min.
