摘要
It is intended to provide a method of preparing sample for matrix-assisted laser desorption/ionization mass spectrometry using a matrix capable of generating preferred crystals that cause effective ionization of a molecule to be measured. A method of preparing a sample for matrix-assisted laser desorption/ionization mass spectrometry comprising the steps of: preparing a solution of 2,5-dihydroxybenzoic acid of 40 mg/mL to saturated concentration as a matrix solution; and dispensing the matrix solution to a sample to be analyzed by using an inkjet mechanism, to crystallize the 2,5-dihydroxybenzoic acid.
