Abstract
Stable hemoglobin A.sub.lc (s-A.sub.lc) can be separated from other hemoglobin components and quantitated in a short time by means of a liquid-chromatographic apparatus comprising a separation column packed with a packing material consisting essentially of a porous substance having a carboxyalkyl group combined thereinto, as ion exchanger, a means for injecting a sample into the separation column, a means for passing one or more eluents through the separation column, and a means for detecting hemoglobin, hemoglobin derivatives or glycosylated hemoglobin, the average particle size of the packing material in dry state being 4 .mu.m or less.
