【摘要】 依照《测量不确定度评定与表示》,对吹扫捕集-气相色谱-质谱法测定水中环氧氯丙烷的结果进行不确定度评定。通过评定可知标准曲线配制过程所引入的相对不确定度最大,吹扫捕集-气相色谱-质谱法测定模拟水样中环氧氯丙烷结果为(78±21)μg/L。更多还原

【Abstract】 Based on Evaluation and Expression of Uncetainty in Measurement,the measurement results of epichlorohydrin in water samples by purge and trap-gas chromatography-mass spectrometry were collected and the measurement uncertainty was evaluated.The results indicated that the main factor were the process of making the standard curve,and the measurement result of epichlorohydrin in simulated water sample by purge and trap-gas chromatography-mass spectrometry was(78±21) μg/L.更多还原
