Application of Thermal Vapor Deposition Method for MALDI-MS : Molecular Weight Determination of Insoluble Sorbitol Derivatives
열증착 시료 제작법이 적용된 MALDI 질량분석법 에 의한 불용성 Sorbitol 유도체의 분자량 결정
Abstract
A thermal vapor deposition method for crystallization of insoluble analysis with matrix is established as a new sample preparation method for matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). A mixture of mono, bis and tris(p-ethyl benzylidene) sorbitols was incorporated into microcrystals of ferulic acid, which was confirmed by confocal micrographs. Molecular masses of sorbitol derivatives were determined in this way by MALDI-MS without thermal decomposition.
