Abstract: In an analysis method of the present invention, a compound represented by the following formula (I) as a matrix is mixed into an analysis target sample and the mixture is subjected to matrix-assisted laser desorption ionization mass spectrometry. In the formula (I), R is an alkyl group having 3-11 carbon atoms. The analysis target sample is a substance for which whether or not β-lactamase is contained is to be determined. Analysis targets include, for example, bacteria and an, extract from bacteria.
