Provided are: a mass spectrometry method using a matrix which can easily and efficiently enhance the ionization efficiency in mass spectrometry even without modifying the molecules to be measured; and a matrix for use in mass spectrometry. A mass spectrometry method using, as a matrix, a 2,4,6- trihydroxyalkylphenone represented by general formula (I) [wherein R is an alkyl group having 4 to 12 carbon atoms]; and a mass spectrometry method as described above, wherein the analysis object is a hydrophobic compound, particularly, a hydrophobic peptide. |
