- •
MS/MS behavior of three the most common mono-caffeoylquinic acids were determined.
- •
Similarities and differences between the dissociation pathways in the positive and negative ionization are illustrated.
- •
The MS/MS in the negative ion mode differentiated the three isomers based on product ion intensities.
- •
ESI-FAIMS-MS/MS successfully separated the three isomers in juice samples with a run time of less than 1 min.
