【摘要】 建立了毛细管气相色谱法测定马来酸氯苯那敏中的乙醇、丙酮、甲苯和DMF的含量。用CP-624色谱柱,柱温采取程序升温。各溶剂的线性关系良好(r均在0.99以上),平均回收率99.8%～101.2%。更多还原

【Abstract】 A capillary GC method for the determination of residual organic solvents——ethanol, acetone, tolueneand dimethylformamide in chlorphenamine maleate was established. A CP-624 column was used with procedural columntemperature control. The calibration curves of four solvents were linear (r>0.99). The average recoveries were 99.8%～101.2%.更多还原
