| 摘 要： | 建立了液体顶空气相色谱法测定盐酸马尼地平中有机溶剂残留量.采用DB-1大口径毛细管柱,以正丙醇为内标进行定量.甲醇、乙醇、异丙醇、乙醚、正丙醇及三氯甲烷的线性范围分别为1.5～61.6μg·mL-1(r=0.9991),04～62.0μg·mL-1(r=0.9994),1.6～64.4μg·mL-1(r=0.9984),1.1～43.6μg·mL-1(r=0.9997)和1.5～63.2μg·mL-1(r=0.9992);回收率分别为99.9%,103.8%,101.8%,97.7%和98.3%;最低检测限分别为0.02μg·g-1,0.04μg·g-1,0.02μg·g-1,0.01μg·g-1和0.2μg·g-1.本方法简单、准确、灵敏度及重现性好.
