【摘要】 HPLC法测定乳糖醇的含量：采用Beckman碳水化合物柱，流动相为重蒸水，柱温90℃，示差折光检测器检测。最低检测限为10μg／ml（S／N=3），在0．25～4mg／ml的范围内呈良好的线性关系，r=0．9994．日内和日间相对标准差均小于3．0％。更多还原

【Abstract】 An HPLC method was used to measure lactitol. It was equipped with a refractive index detecor and a Beckman carbohydrate column. The column temperature was maintained at 90±0. 5 ℃ and the mobile phase was redistilled water. The results showed that the limit of detection was 10 μg/ml (S/N=3), the linear range was 0. 25～4 mg/ml (r = 0. 9994), and the precisions within a day or among d days all were less than 3. 0%.更多还原
