Simultaneous Quantitative Analysis of Four Components of PET Resin Using Near-Infrared Spectroscopy [Technical Document]
Quantification of diethylene glycol, isophthalic acid, intrinsic viscosity, and acid value in PET resin, a type of polyester, using near-infrared spectroscopy.
This document explains the quantitative analysis of diethylene glycol (DEG), isophthalic acid (IPA), intrinsic viscosity (IV), and acid value (TAN) contained in polyethylene terephthalate (PET), a type of polyester. Traditional chemical analysis using conventional reagents requires time to obtain results and relies on the skill of the operator, whereas near-infrared spectrometers can be operated easily and quickly without the need for special skills.
