A method for producing a water-insoluble substance sample for MALDI mass spectrometry and a method for quantitative analysis of a water-insoluble substance using MALDI mass spectrometry.
A method for producing a water-insoluble substance sample for MALDI mass spectrometry and a method for quantitative analysis of a water-insoluble substance using MALDI mass spectrometry.
The present invention relates to a method for producing a sample having a uniform thickness of a homogeneous water-insoluble substance sample, and a method for quantitatively analyzing a water-insoluble substance by performing MALDI mass spectrometry on such a sample. is there. Specifically, the sample is obtained by adding a volatile solvent to a mixture of a water-insoluble substance and a matrix and dispersing the mixture of the water-insoluble substance and the matrix until the solvent evaporates. It can be manufactured by putting it in a pellet cup, pressing it at the same pressure, and then dissolving the pellet cup in water.
