一般說明

LiChrosolv 级别针对LC-MS的适用性进行了精确测试,并可满足现代LC-MS电离方法(ESI/APCI-正负模式)的所有要求。由于其离子背景水平低和离子抑制低,LiChrosolv 级别溶剂可提供高重现性和高电离效率。包装材料已经过改进,可以完美满足LC-MS的质量要求。

應用


  • The composition of chemicals and anti-osteogenic properties in the volatile extracts from Homalomena gigantea rhizome: This study highlights methanol′s role in the extraction and analysis of volatile organic compounds from medicinal plants, providing insights valuable for researchers in pharmacology and natural product chemistry (Thanh et al., 2024).


  • A homochiral tartrate-bridged dinuclear chromium(III) complex anion with a resonance-assisted hydrogen bond for proton conduction: Methanol is used as a solvent in the synthesis of complex inorganic compounds, which are essential in developing new materials for energy applications, such as proton exchange membranes (Dunatov et al., 2024).
