摘要: 以四氯化碳为吸收液采集压缩气体中的油类物质,用红外光度法测定油含量,依据JJF 1059.1-2012《测量不确定度评定与表示》,评定了红外光度法测定压缩气体中油含量结果的不确定度。分析了影响不确定度的因素,对各不确定度分量进行了分析和计算,当压缩气体中油测量结果为5.52mg/m3时,扩展不确定度为0.68mg/m3

关键词: 红外光度计, 压缩空气, 四氯化碳, 油, 测量不确定度

Abstract: After being collected the oil of compressed air by carbon tetrachloride, oil in the compressed air was determined by infrared spectrophotometry. According to Guide to the Evaluation and Expression of Uncertainty in Measurement(JJF 1059.1-2012),the uncertainty of measurement of the content of oil was evaluated. The influence factors of uncertainty were found out,and the components of uncertainty were calculated and evaluated. As the content of oil in compressed air was 5.52mg/m3, the expanded uncertainty was 0.68mg/m3.
