Summary:A separation column is constructed by using disks including cation-exchangeable silica monolith discs (discs M) having an average pore size of 2.0 µm and hydrophobic silica monolith discs (discs O) having an average pore size of 3.0 µm. More specifically speaking, a separation column is constructed by layering the discs M and O in the order of MMMOOO from the upstream side of an HPLC device. By using this separation column, a solution containing stable glycohemoglobin (HbAlc) and unstable glycohemoglobin is separated and measured. As a result, stable HbAlc can be separated at a high resolution ability. L'invention concerne une colonne de séparation construite en utilisant des disques comprenant des disques monolithes de silice à échange cationique (disques M) ayant une taille de pore moyenne de 2,0 µm et des disques monolithes de silice hydrophobe (disques O) présentant une taille de pore moyenne de 3,0 µm. Plus spécifiquement, on construit une colonne de séparation en empilant les disques M et O dans l'ordre MMMOOO en partant du côté amont d'un dispositif HPLC. L'utilisation de cette colonne de séparation permet de séparer et de mesurer une solution contenant de la glycohémoglobine stable (HbAlc) et de la glycohémoglobine instable. Ainsi, on peut séparer l'HbAlc stable avec une capacité haute définition.
