Abstract
In separation column 23 is packed a filler consisting of an inorganic or organic porous substance having carboxyalkyl group and dihydroxyboronyl group. Thus, the separation column 23 can concurrently perform the procedure of separating glycohemoglobin, hemoglobin and hemoglobin derivatives in blood and the procedure of decomposing labile-type hemoglobin in blood into glucose and hemoglobin to remove the labile-type hemoglobin, when a diluted blood sample on sample table 19 along with eluents 8 to 10 is transferred to the separation column 23. Then, stable-type hemoglobin in the eluate from the separation column 23 is measured by UV-VIS detector 25.
