Measurement of resin additives and semi-quantification of unknown peaks using a triple detection system.

Introduction of analysis examples using the Vanquish Core HPLC system for routine analysis.

Resins used in various products in daily life contain a variety of additives to enhance their durability and functionality. Even in small amounts, these additives can compromise the performance of the final product if they remain in it, or lead to the byproducts of undesirable components during the manufacturing process. Additionally, the impact of the leaching of additives on human health is receiving significant attention. Against this backdrop, the importance of identifying and quantifying the additives contained in resins is increasing. In this application note, we conducted an analysis of resin additives using the Thermo Scientific ISQ EC single quadrupole mass spectrometer. Simultaneously, we assumed qualitative and quantitative analysis of byproducts and performed measurements using three detectors, including a diode array detector (DAD) and a charged aerosol detector (CAD). Furthermore, using a dual pump with a reverse gradient method and CAD, we enabled semi-quantification of unknown peaks. For HPLC, we used the Thermo Scientific Vanquish Core HPLC system, which is specialized for routine analysis. This time, we conducted measurements utilizing the capabilities of this device and confirmed its usefulness.
