General description

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。

Application


  • The composition of chemicals and anti-osteogenic properties in the volatile extracts from Homalomena gigantea rhizome:本研究中,甲醇用于药用植物来源挥发性有机化合物的提取和分析,为药理学和天然产物化学的研究人员提供宝贵参考(Thanh et al., 2024)。


  • A homochiral tartrate-bridged dinuclear chromium(III) complex anion with a resonance-assisted hydrogen bond for proton conduction:在复杂无机化合物的合成中使用甲醇作为溶剂。这类无机物在新能源材料(如质子交换膜)的开发中发挥重要作用(Dunatov et al., 2024)。
