Abstract

See full text

The present invention relates to a method for producing test pieces in which the thickness of the samples of homogeneous water-insoluble material is uniform, and to a method for quantitative analysis of water-insoluble material by analyzing such test pieces using MALDI mass spectrometry. Specifically, the test pieces can be produced by: adding a volatile solvent to a mixture of water-insoluble material and matrix; placing, in a pellet cup made of water-soluble material, and pressing, with even pressure, the sample obtained by mixing the mixture of water-insoluble material and matrix until the solvent has evaporated; and melting the pellet cup with water.
