液相色谱串联质谱法测定包装材料中全氟辛烷磺酸不确定度的评定
Uncertainty Evaluation for Determining PFOS in Packaging Material by LC/MS
摘要
Abstract
The uncertainty and the influenced factors for the determination of PFOS in packaging material by LC/MS have been analyzed by mathematical expressions.At the same time the components of the standard uncertainty were analyzed and calculated.And the result indicted that the major factor of uncertainty in meas-urement is preparing standard solution.Then the results were combined and expanded ,thus the content of in packaging material is (1.590 ±0.079) μg/m2 ,k=2.关键词
