Capillary Zone Electrophoresis for the Analysis of Phenolic Preservatives in Plasma and Insulin Formulations Using Salting‐Out Assisted Liquid–Liquid Extraction

ELECTROPHORESIS, EarlyView.
A rapid and reliable SALLE–CZE–UV method was developed for the determination of phenolic preservatives in insulin formulations and human plasma. The approach provides efficient extraction, fast separation (< 6 min), and excellent sensitivity, precision, and recovery, meeting regulatory requirements for accurate quantification.
