Disclosed is a probe for mass spectrometry of liquid samples, which may effectively ionize the sample without adding a protic solvent to the mobile phase in the ionization method in mass spectrometry of liquid samples. The probe according to the present invention has a structure represented by the Formula [I]: <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>2</SUP>-A-R<SUP>1</SUP>[I]<?in-line-formulae description="In-line Formulae" end="tail"?> (wherein R<SUP>1 </SUP>represents an ionic functional group which becomes an ion in a solvent, R<SUP>2 </SUP>represents a structure which can bind to other substance, and A represents an arbitrary spacer moiety). |
