一般描述

MALDI-MS分析需要最高纯度的基质和试剂，因为有机或痕量金属污染会在结晶、电离或测量过程中造成不良影响。因此，我们的 MALDI 基质和试剂（如 2′,4′,6′-三羟基苯乙酮一水合物）是为了满足如今′严苛应用的要求而设计的。

应用

在基质辅助激光解吸/电离飞行时间质谱(MALDI/TOF)中，2′,4′,6′-三羟基苯乙酮一水合物已被用作寡糖和糖肽分析的基质。[1]
用于负离子模式的酸性聚糖和糖肽的MALDI分析。检测下限低于6-氮杂-2-硫代亚胺。[2]

    2,5-Dihydroxybenzoic acid (DHB) is the most commonly used matrix for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI/TOF) of oligosaccharides. Because acidic, sialylated oligosaccharides are detected at only the low picomole level with DHB, alternative matrices were screened to identify a
