Uncertainty evaluation of the detection result from determination of water-extractable proteinin natural rubber latex
天然乳胶水抽提蛋白质含量检测结果不确定度评定

摘要

本评定对标准GB/T 21870-2008用于测定块状乳胶产品的水抽提蛋白质含量进行不确定度分析，从多方面去分析其方法的不确定度构成和贡献。最终计算得一份蛋白质含量为805.29μg/g 的扩展不确定度为197.94μg/g（k=2）。

Abstract

This assessment conducts uncertainty analysis on the standard GB/T 21870-2008 for the determination of water-extracted protein content in bulk latex products, and analyzes the uncertainty composition and contribution of its method from various aspects. Finally, the expanded uncertainty of a protein content of 805.29 μg/g was calculated to be 197.94 μg/g (k=2).
