Machine Learning–Based Optimization of Phthalate Extraction Conditions Using HS‐INME‐GC/MS Data

Journal of Chemometrics, Volume 40, Issue 10, October 2026.
ABSTRACT Optimization of extraction conditions in GC/MS analysis remains challenging because experimental variables can interact in complex and nonlinear ways. In this study, a machine learning based chemometric workflow was applied to optimize headspace in‐needle microextraction GC/MS (HS‐INME‐GC/MS) conditions for four phthalates: dimethyl phthalate (
