On-line liquid chromatography-electrospray ionisation mass spectrometry for kappa-carrageenan oligosaccharides with a porous graphitic carbon column

J Chromatogr A. 2007 Apr 13;1147(1):37-41. doi: 10.1016/j.chroma.2007.02.023. Epub 2007 Feb 11.

Abstract

Enzymatically digested oligosaccharides of kappa-carrageenans were separated on a porous graphitic carbon (PGC) column and characterised on-line by electrospray ionisation mass spectrometry (ESI-MS). Two different developing ions were applied. Among them ammonium hydrogencarbonate showed more eluting power as it should on normal anion-exchange stationary phases. The oligosaccharides were detected by ESI-MS as fully deprotonated oligosaccharides.
