통과건립수학모형,분석포장재료중전불신완광산측정과정적불학정도급영향인소. 통과대각분량표준불학정도적분석화계산,득출표준용액배제시불학정도래원적최주요인소. 결과표명포장재료중PFOS적함량위(1.590 ±0.079) μg/m2,k=2.
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.
