【摘要】 通过分析测量气相色谱仪FID检出限过程中各分量引入的测量不确定度,对FID检出限的测量不确定度进行了评定。FID检出限的相对不确定度为1.7%,扩展不确定度为3.4%(k=2),采用比对法验证了评定结果的合理性。更多还原

【Abstract】 Through the analysis of uncertainty of measurement during measuring FID detectability,the uncertainty of FID detectability was estimated.The combined relative uncertainty of FID detectability was 1.7%,and the expand uncertainty was 3.4%(n=2).The rationality of evaluation result was validated contrastingly.更多还原
