General

YMC*Gel Silica is a fully scalable highly pure silica gel, which provides excellent lot-to-lot reproducibility and high sample recoveries. The totally porous spherical particles are mechanically and chemically stable, yet provide high surface area for greater sample loading and increased resolution.

Properties

High purity YMC*Gel Silica combines premium performance, excellent batch-to-batch reproducibility and long column life times. The homogeneous surface, the narrow and symmetrical pore size distribution, and the narrow particle size distribution provide excellent separation characteristics and a low pressure drop.

The totally porous nature of YMC*Gel Silica provides a very high surface area for greater sample loading and increased resolution.

In addition YMC*Gel Silica allows high yields and optimal sample recovery. This is because YMC*Gel Silica is virtually free from impurities, e.g. heavy metals, which can cause non-specific sample adsorption and so lower sample recovery.

Despite its high level of porosity YMC*Gel Silica shows exceptional mechanical properties. The mechanical strength of the spherical particles prevents the formation of fines and high back pressure. Therefore, YMC*Gel Silica is excellent for use in all kinds of dynamic axial compression systems. Furthermore, the mechanically and chemically stable YMC*Gel Silica is the ideal support material for YMC bonded phase chemistries.

YMC*Gel Silica is completely scalable: YMC offers numerous specifications for preparative LC in the range between 10 and 150 µm at large lot size production, in excess of 500 kg/batch.
