Abstract
The present invention provides a mass spectrometry method using a mixed matrix, capable of easily and efficiently improving the ionization efficiency in mass spectrometry for peptides having a wide range of degrees of hydrophobicity (from hydrophilic to hydrophobic). A MALDI mass spectrometry method for analyzing a sample using as a mixed matrix, 2,4,6-trihydroxyalkylphenone represented by the following general formula (I): wherein R represents an alkyl group having 3 to 12 carbon atoms, and a matrix (II) for mass spectrometry that is more hydrophilic than 2,4,6-trihydroxyalkylphenone represented by the formula (I) wherein R is an alkyl group having 3 carbon atoms.
