METHOD AND MATERIAL FOR ADSORPTION PREVENTION, INNER-WALL-COATED CAPILLARY, ITS MANUFACTURING METHOD, AND METHOD FOR SIMULTANEOUS ANALYSIS OF PHOSPHATE COMPOUND AND ANION

摘要

PROBLEM TO BE SOLVED: To easily and highly durably prevent the adsorption of phosphate compounds.

SOLUTION: A polymer solution containing a phosphatide polymer in which MPC and SMA or MPC and BMA are combined is flowed through a capillary 10 containing silanol in its wall surface to achieve an inner-wall-coated capillary in which a zwitter ion type polymer containing a phosphate group made of, for example, a phosphorylcholine group 12 is immobilized to the wall surface containing silanol by ionic interaction.
