摘要
本文报道了以峰鉴别技术为定性依据的测定火锅汤料中微量吗啡的反相高效液相色谱法.本法采用改良的Stas-otto法分离提取复杂样品中的微量吗啡.由于采用峰鉴别技术,增加了定性参数,大大提高了定性方法的准确性.本法简便、快速.最低检出浓度为0.04mg/L.在数十例样品分析中,与其它仪器分析结果比照,非常符合.
The morphine in chafing dish soup was extracted by a modified Stas-otto method, and determined by reversed-phase HPLC. The peak identification technique was used to get reliable qualitative result. The minimum detectable amount is 0. 04 mg/L, and the results are agreement with those obtained from the oscilloscopic polarography.
