Abstract:
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.

Claim (Index 7):
Mass spectrometry using near infrared (NIR) fluorescence, comprising:\n placing a sample, which includes a fluorescent material having an excitation wavelength of an NIR wavelength band and a matrix for ionization, on a plate; acquiring, by a fluorescence detection unit, a fluorescence image by using the fluorescent material from the sample on the plate; emitting, by a light emission unit, a laser beam for ionization at the sample on the plate; and detecting, by an ion detection unit, ions generated from the sample by using the laser beam.
