In the analysis of hemoglobins in blood samples by chromatography, an increase in the pressure in a flow passage line is suppressed, a separation column is made durable against prolonged use by supplying phosphate-based buffer solutions as eluting solutions to a separation column and a solution containing not more than 100 mM of S-(carboxyalkyl)-L-cysteine and phosphate-based buffer agent thereto in the course of a series of analyzing steps.
