- •
A novel LC-MS/MS method was developed for EDTA quantification in wines.
- •
Amines were applied to convert EDTA into its stable EDTA-amine complexes.
- •
Primary amines can improve sensitivity by eliminating metal ions interference.
- •
Phenylboronic acid eliminated the matrix interference from reducing sugars.
