Abstract
A method for analyzing vanillylmandelic acid, homovanillic acid and creatinine by fast liquid chromatography, which includes a step of introducing a test solution containing vanillylmandelic acid, homovanillic acid and creatinine to a cation exchange resin column and separating creatinine from vanillylmandelic acid and homovanillic acid; a step of separating by a separation column vanillylmandelic acid and homovanillic acid in the test solution from which creatinine has been separated; and a step of detecting each component.
