QUANTIFICATION OF MASS SPECTROMETRY USING TOTAL REFLECTION LASER IRRADIATION METHOD

摘要

PROBLEM TO BE SOLVED: To quantitatively count the number of the molecules of a sample by irradiating the sample with evernescence light without using a matrix in mass spectrometry.;SOLUTION: A laser beam is introduced into a trapezoidal prism in parallel to the base of the prism and totally reflected by the inner surface of the base of the prism to generate evernescence light from the outer surface of the base. The sample applied to the outer surface is evaporated by the evernescence light to perform the quantitative analysis of the sample.;COPYRIGHT: (C)2007,JPO&INPIT
