PROBLEM TO BE SOLVED: To provide a quantification method for additive that can quantify an additive without reference to the kind of a base material polymer.SOLUTION: The quantification method includes the steps of: (a) obtaining a characteristic value of a first polymer molding whose additive content is already known by dividing a peak area, originating from an additive, which appears in a chromatogram of a prepared first sample from the first polymer molding by the mass of the first sample; (b) obtaining a function BL using the characteristic value and content of the first polymer molding; (c) obtaining a characteristic value of a second polymer molding whose additive content is not known by dividing a peak area, originating from an additive, which appears in a chromatogram of a prepared second sample from the second polymer molding by the mass of the second sample; and (d) obtaining the contents of the additive included in the second polymer molding using the characteristic value of the second polymer molding and the function BL. |
