PROBLEM TO BE SOLVED: To provide a sample substrate for measuring soft LDI-MS capable of performing accurate measurement of high sensitivity without producing an obstruction peak when irradiated with a laser beam and capable of uniformly coating a sample in forming the sample in a sample substrate for analyzing laser eliminated ionization mass.;SOLUTION: In the sample substrate 50 subjected to the laser eliminated ionization mass analysis, the sample substrate is constituted so that carbon nanowalls 55 are vertically provided on a base stand and the surfaces of the carbon nanowalls are coated with the sample for mass analysis. The surfaces of the carbon nanowalls act as an ionizing medium with respect to the sample and is subjected to hydrophilizing treatment. By this constitution, a stable mass analysis of good precision and high sensitivity can be realized over a wide range from a low molecular weight to a high molecular weight.;COPYRIGHT: (C)2011,JPO&INPIT
