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。

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。

Nucleic acids research, 21(14), 3191-3196 (1993-07-11)

We report the analysis and characterization of natural and modified oligonucleotides by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). The present technology was highly improved for this class of compounds by using a new matrix, 2,4,6-trihydroxy acetophenone, together

A novel binary matrix consisting of graphene oxide and caffeic acid for the analysis of scutellarin and its metabolites in mouse kidney by MALDI imaging.

The Analyst, 146(1), 289-295 (2020-11-04)

Although the in vivo metabolic pathways of scutellarin, a traditional Chinese medicine, have been investigated via different liquid chromatography techniques, studies on the distribution and location of scutellarin within organ tissue sections have not been reported. Matrix-assisted laser desorption/ionization mass

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
