茶叶中氟成分分析标准物质是为生物样品中氟定量分析的质量控制提供可靠的科学依据。标准物质的稳定性是指定值的特征量随时间的变化情况。报道了灰化蒸馏—氟试剂比色在茶叶中氟定值量稳定性的结果。
The fluorine component analysis standard in tea provides a reliable scientific basis for the quality control of fluorine quantitative analysis in biological samples. The stability of the reference material is the change of the characteristic value of the specified value with time. The result of the stability of the FFA value in tea leaves by the gray distillation-Fluorometric reagent colorimetry was reported.
