| 中文摘要: |
| 目的：建立原子吸收法测定明胶空心胶囊中铬元素不确定度评定的方法。方法：采用《中国药典》2015年版收载明胶空心胶囊铬元素测定的方法，找出影响测定结果的各个分量并量化各组成标准不确定度，评定测定结果的不确定度。结果：原子吸收测定明胶空心胶囊铬元素的不确定度为1.395±0.08487 μg·mL-1（k=2）。结论：本方法简便易行，可用于原子吸收法测定明胶空心胶囊中铬元素的不确定度评定。 |

| Objective: To establish a method for uncertainty evaluation on chromium determination of vacant gelatin capsules by the atomic absorption spectrometry. Methods: With the method for chromium determination of vacant gelatin capsules in Chinese Pharmacopoeia 2015 edition, the factors influencing the measurement results were found out and the standard uncertainty of each component was quantified to assess the uncertainty of the measurement results. Results: The expanded standard uncertainty for the chromium determination of vacant gelatin capsules with AAS was 1.395±0.08487 μg·mL-1(k=2). Conclusion: The method appears to be easily operated and suitable for assessment of uncertainty in chromium measurement of vacant gelatin capsules with Atomic Absorption Spectrometry. |
