Abstract:

Sulfonamides (SAs) are prohibited substances in cosmetics. An ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QTrap) method using precursor ion-information dependent acquisition-enhanced product ion (PIS-IDA-EPI) scanning mode was developed to screen SAs in cosmetics. Twenty SAs were investigated to identify their common product ions formed by collision-induced dissociation. Three common positive product ions, m/z 92, m/z 108, m/z 156 are selected for PIS analysis. Limits of detection (LODs) are 0.05-0.1 μg/g for all 20 SAs in 12 kinds of cosmetic matrix. Sixty samples are analyzed. An effective screening method using UPLC-QTrap with PIS-IDA-EPI acquisition mode is developed and successfully applied to screen for the targeted and untargeted SAs in cosmetic samples.

Key words: sulfonamides (SAs), cosmetics, triple quadrupole/composite linear ion trap mass spectrometry (QTrap), precursor ion scan (PIS)
