卤素含量是影响电线电缆材料性能的关键指标之一,因此需精确测定以实现精细的产品质量控制和职业安全.离子色谱法通常用于量化卤素含量,其准确性和真实性取决于各种因素,如仪器精度、样品制备和标准物质选择.剖析了影响离子色谱分析结果的变量,建立了一个不确定度评估模型,并用实际样品对不确定度进行了量化.实验结果表明,仪器精度和样品制备是使用离子色谱法测量电线电缆材料中卤素含量的不确定度的主要来源.通过微调实验条件和加强质量控制,减少不确定度并提高测量的精度和可靠性是可行的.
Uncertainty Estimation for Ion Chromatographic Determination of Halogen Content in Cable Materials
Halogen content is one of the key indexes that affect the performance of electric cable materials,and thus needs to be accurately determined to achieve fine product quality control and occupational safety.Ion chromatography is usually used to quantify halogen content,and its accuracy and authenticity depend on various factors,such as instrument accura-cy,sample preparation,and selection of reference materials.This work established an uncertainty estimation model based on analyzing the aforementioned variables,and the uncertainty was quantified with actual samples.The results showed that the instrument precision and sample treatment process could be regarded as the main sources of uncertainty in ion chromatographic determination of halogen content in cable materials.It is feasible to reduce uncertainty and improve accu-racy and reliability of measurement by fine-tuning of experimental conditions and strengthening quality control.
