Popis:	A high-performance liquid chromatographic (HPLC) method to determine the d -mannuronate/ l -guluronate (M/G) ratio in alginates is described. Comparison between the HPLC procedure and a proton magnetic resonance method is made. The HPLC procedure can be used to determine the absolute M/G ratio in some sample types. In others it needs calibration against a method such as proton magnetic resonance.
