Data provided by Flavio A. Franchina (1), Mariasora Maimone (2), and Luigi Mondello (1,2) of (1) Chromaleont s.r.l., c/o “Scienze del Farmaco e Prodotti per la Salute” Department, University of Messina, viale Annunziata, 98168 Messina, Italy or (2) “Scienze del Farmaco e Prodotti per la Salute” Department, University of Messina, viale Annunziata, 98168 Messina, Italy.
The chromatogram shown here represents research toward the development of a flow-modulation comprehensive 2D GC/MS (FM GCxGC/MS) method for the determination of recently indicated allergens in fragrances. The detector was a rapid-scanning single quadrupole MS (quadMS). SLB-5ms and SLB-35ms GC columns were used. Mass spectral matching was carried out by using the FFNSC database.
