|Abstract:||During systematic studies of the behavior of oligogalacturonic acids (OGAs) under different conditions using electrospray ionization mass spectrometry (ESI-MS), cation adduction, fragmentation and non-covalent binding were found to be the three major problems that compromised the analysis of OGAs by ESI-MS. By adjusting solution components, capillary temperature and capillary voltage in the ESI source, an optimized condition was found that gave a clean and clear spectrum of trigalacturonic acid. A direct injection ESI-MS technique based on the use of aqueous acetonitrile and acetic acid and triethylamine (TEA) as modifiers has been applied to analyze a mixture including mono-, di- and trigalacturonic acids, which will facilitate further applications of ESI-MS in the analysis of mixtures of OGAs. © 2001 John Wiley & Sons, Ltd.|
