Beschreibung

Allgemeine Beschreibung

Standardized sorbents ensure reliable results every time. Our broad spectrum meets all kinds of needs. In TLC, silica gel 60 sorbent is considered the most versatile. Our assortment of silica gel 60 features different grades with particle sizes ranging from 5-40 µm: silica with a gypsum binder, silica with no foreign binder, and silica gel with a fluorescence indicator. We also offer high-quality aluminum oxide, cellulose microcrystalline, and kieselgur (also known as diatomaceous earth).

Anwendung

• A rapid preparative method for isolation of neutral and acidic glycosphingolipids by radial thin-layer chromatography.: This study outlines a swift and efficient preparative method using radial thin-layer chromatography to isolate both neutral and acidic glycosphingolipids, utilizing Silica gel 60 PF254. The methodology enhances the purity and yield of the glycosphingolipids isolated, contributing significantly to advancements in analytical chemistry techniques (Das KK et al., 1984).
