Popis

General description

LiChrosolv hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.

Application

• 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).
