[Analysis Case] Evaluation of Additives in Polymer Materials Using Dissolution-Reprecipitation Method

Qualitative analysis of components using LC/MS and LC/MS/MS.

When analyzing additives used in polymer materials such as resin products, it is necessary to separate the polymer materials from the additives. We will introduce a case where a sample pre-treated using the "dissolution-reprecipitation method," which involves dissolving commercially available resin products in a solvent and then precipitating the polymer components to extract the additive components, was analyzed. The results of the LC/MS analysis indicated that a component with a high abundance (m/z=548.50) was estimated to be a type of phenolic antioxidant through LC/MS/MS analysis.
