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]:
R
2
-A-R [I]
(wherein R
1
represents an ionic functional group which becomes an ion in a solvent, R
2
represents a structure which can bind to other substance, and A represents an arbitrary spacer moiety).
揭示了一种用于液体样品质谱的探针,可以在液体样品的质谱离子化方法中有效离子化样品,而无需向移动相中添加质子溶剂。根据本发明的探针具有以下式所表示的结构:
R2-A-R [I]
(其中R1代表在溶剂中成为离子的离子功能团,R2代表可以结合到其他物质的结构,A代表任意的间隔基团)。
