【摘要】 验证了卡尔费休容量法对血管封合剂水分含量测定的准确性和可靠性。标准工作曲线的线性相关系数r=0.9999,检出限为0.075 mg。采用加标回收率,实验结果为回收率97.19%～99.62%。对同一样品平行测定6次,相对标准偏差为3.66%。更多还原

【Abstract】 To verify the accuracy and reliability of Karl Fischer volumetric method of vascular Sealant moisture content measurement.The linear correlation coefficient of standard working curve was 0.9999.The detection limit of this method was 0.075mg.The results were obtained by using the recovery which were 97.19%~99.62%.The same samples were parallel determined by 6 times,and the relative standard deviation was 3.66%.更多还原
