Rapid Detection of Plasticizer Migration From UV-Aged PVC Films by DART-HRMS.

ABSTRACT:

Rationale

The migration of phthalate plasticizers from high-volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time-consuming solvent extraction and chromatographic methods that are often expensive and lack the throughput required for large-scale safety screening, this study intends to present a rapid screening method using direct analysis in real time coupled to high-resolution mass spectrometry (DART-HRMS) to monitor plasticizer migration in PVC films subjected to accelerated UV aging. Operational parameters, such as ionization gas temperature and grid voltage, were systematically optimized to balance desorption eff
