【摘要】 目的:建立一次性使用无菌医用口罩中环氧乙烷残留量测定的不确定度评定方法。方法:采用气相色谱法测定一次性使用无菌医用口罩中环氧乙烷的残留量,并对结果的不确定度进行评定。结果:扩展不确定度U 95为0.27μg/ml,覆盖因子为k=2。结论:由于为痕量的限度检测,采用不确定度对结果进行评定,使结果更加准确。更多还原

【Abstract】 Objective:To establish an uncertainty measurement method of epoxy ethane in sterile medical masks for single use.Methods: epoxy ethane residues in sterile medical masks for single use were determined by gas chromatography,and the uncertainty of the measurement was evaluated.Results:the expanded uncertainty U 95 was 0.27 μg/ml,with a coverage factor k=2.Conclusion: due to the limit detection of trace,it makes the result more accurate to use uncertainty evaluation for the determination results.更多还原
