Silica Gel

Dynamic Adsorbents’ silica gels are carefully manufactured and quality assured to provide the ideal laboratory and pilot process chromatographic material. As with alumina, independent tests have shown that DAI produces the highest quality silica gel on the market today.

In addition, we carefully control the manufacturing process from raw material to finished product including physical characteristics of pore size, surface area, particle size and surface chemistry to ensure reproducible optimized chromatographic behavior for uniform capacity, reproducible selectivity, improved resolution and excellent performance. When it comes to silica gel, we are the only vendor in the industry performing a detailed analysis on each lot of silica gel provided to the customer.

Dynamic Adsorbents, Inc. distributes high quality silica gels for column chromatography and/or TLC with the lowest everyday price to many research institutions, pharmaceutical companies, and organic synthesis labs. DAI’s bulk silica gels are used for low pressure and high pressure columns. DAI’s silicas have virtually no traces of metals contained within, and the particle distribution is kept extremely tight for reproducible results. All silicas can come with MSDS sheets, as well as Certifcates of Analysis if requested. Dynamic Adsorbents, Inc. silica gels are carefully manufactured and quality assured to provide the ideal laboratory and pilot process chromatographic material.

Reproducible performance is delivered regardless of the technique used, especially when transferring from one technique to another. Silica gel is an ideal media for column chromatography for several different reasons. Silica gel has a very strong affinity for water, which gives it an adsorption capacity of over 40% of its own weight at 100% relative humidity. It is compatible with most materials except strong alkalis and hydrofluoric acid. Adsorbent particle size affects how the solvent flows through the column. Smaller particles (higher mesh values) are used for flash chromatography, larger particles (lower mesh values) are used for gravity chromatography.
