Study of XAD-2 adsorbent for the enrichment of trace levels of phthalate esters in hydroalcoholic food beverages and analysis by gas chromatography coupled with flame ionization and ion-trap mass spectrometry detectors

- Solid phase extraction with XAD-2 as stationary phase for determining PAE.
- PAE determination in solutions at very large alcoholic range (10-40 alc vol−1).
- GC-FID analysis and peak confirmation by GC-IT/MS analysis.
- LOD and LOQ lower than those reported in literature with other techniques.
- Procedure can be applied for routine application in any laboratory.
