METHOD AND APPARATUS FOR ANALYZING COMPOUNDS WITH AMINO GROUP

摘要

The present invention provides a method and apparatus for analyzing compounds with amino group(s) contained in biological organisms. In this method, a compound with amino group(s) is derivatized and then the derivative of the compound with amino group(s) is eluted by liquid chromatography using a stepwise elution means on a concentration gradient. Subsequently, the derivative of the compound with amino group(s) eluted from the liquid chromatography is detected by mass spectrometry.
