文摘
- •
Analyte/matrix covalent adducts were formed during MALDI of nitroxide-terminated P4VP.
- •
A “high pressure” MALDI source and acidic matrices favored this reactive MALDI process.
- •
Incorporation of a matrix molecule in P4VP chain termination was evidenced by MS/MS.
- •
These undesired MALDI by-products can be avoided by using non acidic matrices.
