Descripción

Descripción general

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Aplicación

• 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).
