Investigations of beta-carotene radical cation formation in infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI)
RAPID COMMUNICATIONS IN MASS SPECTROMETRY, 35(16).
MeSH headings : Cations / analysis; Cations / chemistry; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization / methods; Tandem Mass Spectrometry; beta Carotene / analysis; beta Carotene / chemistry
TL;DR:
There are several potential mechanisms for β-carotene radical cationization prior to IR-MALDESI analysis with multiphoton-ionization, thermal degradation, and/or reaction with oxygen, but changing certain aspects of sample conditions can result in significant mixed-mode ionization with competing protonation.
