  • Patent number: 5571729
    Abstract: This invention is intended to provide a process by which a complex formed by the interaction between one or more analytes to be measured and affinity substance can be more effectively separated from substances existing together therewith which tend to affect the detection of the complex, for example, free affinity substance, by using high pressure liquid chromatography (HPLC); and a process for measuring a trace component by utilizing said separating process.This invention is characterized in that a substance which has been modified with a substance capable of changing properties of the complex (a separation-improving substance) and has affinity for the complex is attached to the complex. Because of this characteristic, the invention is effective in that the position of elution of said complex in the HPLC can be freely controlled.
