Ion-pair chromatography method, useful for, e.g. detecting neuroblastoma markers, where the amine in the mobile phase and the solid phase have same alkyl chain length

摘要

Method (M) for analyzing organic substances (I) by ion-pair chromatography, comprises using a mobile phase containing a quaternary amine (II) that has at least one substituent in which the hydrocarbyl chain length is the same as that of the hydrocarbyl chain on the solid phase.
