IONIZATION SUBSTRATE FOR MASS ANALYSIS AND MASS ANALYZER

摘要

PROBLEM TO BE SOLVED: To provide a sample substrate for laser desorption ionizing mass analysis and soft LDI-MS measurement which enables the accurate measurement without forming an obstruction peak at the time of irradiation with a laser beam, and the uniform coating of a sample at the time of production of the sample, and a measuring instrument using it. SOLUTION: As an ionizing medium for absorbing a laser beam used in laser desorption ionizing mass analysis, specified ionization element having a dot structure is used. COPYRIGHT: (C)2007,JPO&INPIT
