| 摘 要： | 采用超临界流体色谱(SFC)测定了饲料中D-泛酸钙的含量.在二氧化碳流动相中添加14.85%甲醇改性剂及0.15%三氟乙酸添加剂,流速2 mL/min,在Kromasil ODS柱上分离,检测波长为210 nm.结果表明D-泛酸钙能在3 min内完成分离,在1.0 ～25.0 mg/L范围内,样品的质量浓度与色谱峰面积呈良好的线性关系(r=0.999 5).方法的精密度良好,相对标准偏差在2.3%以内,回收率为89% ～98%.方法操作简单,结果准确,适合普及应用.

| Abstract: | A supercritical fluid chromatographic(SFC)method for the determination of D-calcium pantothenate in animal feeds was developed.The experimental conditions were investigated.The result indicated that the analysis D-calcium pantothenate could be performed in 3 min on the Kromasil ODS column using a mixture of CO2 and 14.85% methanol(contained 0.15% trifluoroacetic acid) as mobile phase at a rate of 2 mL/min.The UV detector was set at a wavelength of 210 nm.The calibration curve was linear in the range of 1.0-... |
