Patent number: 10481086Abstract: A mass spectrometer using near infrared (NIR) fluorescence can comprise: a plate formed such that a sample, which includes a matrix for ionization and a fluorescent material having an excitation wavelength of an NIR wavelength band, is loaded thereon; a fluorescence detection unit formed so as to acquire a fluorescence image by using the fluorescent material from the sample on the plate; a light emission unit formed so as to emit a laser beam for ionization at the sample on the plate; and an ion detection unit formed so as to detect, by using the laser beam, ions generated from the sample. By using the NIR fluorescence, fluorescence interference due to a matrix used for MALDI imaging can be excluded even after coating the matrix, and since fluorescence interference due to auto-fluorescence inside tissue is low, fluorescence can be measured even for a thick sample.Type: GrantFiled: October 28, 2016Date of Patent: November 19, 2019Assignee: ASTA CO., LTD.Inventors: Jooyeon Oh, Yang Sun Kim
