PROBLEM TO BE SOLVED: To provide a bis-amide quantitative method capable of analyzing the amount of a bis-amide contained in a resin as a lubricant for a short time. SOLUTION: This bis-amide quantitative method using an absolute calibration curve method is characterized in that a resin containing the bis-amide is dissolved in a solvent and the concentration of the bis-amide in the prepared resin solution is readjusted so that the bis-amide is stably dissolved in the solvent to obtain a sample for determination which is, in turn, subjected to gas chromatography/mass analysis to separate and detect the bis-amide.
