摘要
本文建立了天然胡萝卜素胶丸中有机溶剂残留量的气相色谱测定方法,用石英大口径毛细管HP-1柱(0.53mm×30m),氢火焰离子化检测器进行检测,在0μg/ml^1000μg/ml范围内,R=0.9991,呈良好的线性关系,检测限为0.10mg/kg。该法操作简便、快速、准确性高、重复性好,对同一样品的4次平行测定的相对标准偏差(RSD)<3.0%。
Gas chromatographic method for quantitative determination of organic solvent residue in β-carotene capsules on HP-1 （30 m × 0.53 mm） column is studied. Result showed the linear range is in 0 μg/ml - 1000μg/ml with r = 0.9991 and the relative standard deviation is 〈3.0 % （n=4）. The method is simple, rapid, accurate and precise, and the limit of detection is 0.10 mg/kg.
