マトリックス効果の機構解析 ～単純溶媒系でのアミノ酸混合物の気化過程の評価～
The goal of this study was to elucidate the mechanisms of ‘’matrix effect ‘’ to overcome/control its negative influences on ESI measurements. We examined the influence of a matrix molecules on ESI intensity of analytes in simple model systems. Mixtures of two amino acids having different hydrophobicities were analyzed by flow-injection LC/MS. It was found that the ESI signal intensity of analyte was enhanced or suppressed depending on the hydrophobicities of matrix molecules.
