Abstract:
A method for analyzing an antioxidant content contained in a semiconductive material for a cable, which includes an amine-based antioxidant. The method can provide an accurate quantitative analysis value obtained by a comparison with the actual amount used, through gas chromatography (GC)/a flame ionization detector (FID).
