PURPOSE:To enhance analytical preciseness, by providing a removing apparatus due to a dialytic principle for removing or reducing a component not suitable for detecting an analytically objective component present in an elution liquid between a separation column and a detector. CONSTITUTION:The elution liquid in an elution liquid tank 1 is flowed so as to be passed through a specimen injector 3, a separation column 4, a removing apparatus 5, an immobilized enzyme column 8 and a detector 9 by a pump 2 and, at the same time, the reaction liquid in a reaction liquid tank 6 is sent by a pump 7 to be combined with the elution liquid stream at a point before the immobilized enzyme column 8. The removing apparatus 5 has such a structure that a hollow pipe 51 having dialyzability is immersed in a solution having a composition prepared by removing a removal objective component considered not suitable for detection from the composition of the elution liquid and the removal objective component is penetrated and diffused into the solution from the pipe wall according to a dialytic principle during the passage of the effluent liquid from the separation column 4 through the hollow pipe 51. |
