7. Wakogel® Series

Wakogel® Series ⇒ See the properties (page #21~22).

It is the most typical irregular support with high physical strength, and is widely used as a fi ller for column chromatography. Silica gel itself is mostly used in adsorption chromatography for neutral and acidic samples. ODS fi ller that contains chemically-bound silica gel and hydrophobic silylation agents, etc. has also been used widely in the field of column chromatography in recent years due to its extensive applications for reverse phase chromatography.

Wakogel® C18 Series (for Flash Chromatography) ⇒ See the properties (page #21~22).

When samples are neutral and have 1 or 2 functions, an activated thin layer is used to develop in single or multiple solvent systems. When samples are organic base, a small amount of ammonia or diethylamine is added to a developing solvent. When it is used to separate acidic compounds, a small amount of acetic acid is added. When developing solvents containing water, there is no need to mix Wakogel with water and to thermally activate after thin layer preparation.
