摘要: Oligomannuronic acids and oligoguluronic were prepared by enzymatic hydrolysis of alginate with lyases. The oligosaccharides generated up to degree polymerization 16 characterized high-performance anion-exchange chromatography (HPAEC) pulsed amperometric detection (PAD) electrospray ionization mass spectrometry (ESI-MS). Acetate buffer linear gradients used as mobile phases for separations oligosaccharides. ESI-MS HPAEC-PAD are very effective the analysis characterization anionic
