Evaluation of Methylisothiazolinone (MI) Extraction from Sunscreen using Supported Liquid Extraction prior to GC/MS Analysis.

摘要

This poster demonstrates the suitability of ISOLUTE SLE+ for the rapid and reliable extraction of methylisothiazolinone from sunscreen at a relevant concentration, prior to GC/MS analysis. The optimized method offers almost high analyte recoveries with RSDs below 10%, demonstrating excellent chromatographic baseline and visual cleanliness. The BeadRuptor 24 offers greater homogeneity when mixing sunscreen matrix compared to manual vortex mixing.
