Application

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。

General description

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。

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is a powerful new technique that will have a great impact on food analysis. This study is the first to demonstrate the applicability of MALDI-MS to perform both qualitative and quantitative analyses of anthocyanins

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

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
