三七总灰分与酸不溶性灰分的标准值及不确定度评价
Evaluation of Standard Value and Measurement Uncertainty for Determination of Panax Notoginseng Total Ash and Acid-insoluble Ash
摘要
Abstract
Objective To establish an evaluation of standard value and measurement uncertainty of total ash and acid insoluble ash from Panax notoginseng. Methods To establish a mathematical model for calculating standard value and measurement uncertainty of panax ash and acid insoluble ash by analyzing various factors affecting measurement. Results The standard value and expanded uncertainty of panax ash and acid insoluble ash were (3. 83 ±0. 39 ) % and (0.21 ±0.04)%. Conclusion The method created show traceability and can be used to assign standard value for Chinese herbal medicine.关键词
