SILICA GEL (Silicon Dioxide, or SiO2):

Silica Gel (silicon dioxide) is a chemical composed of silicon and oxygen (SiO2), and consists of an amorphously structured porous matrix. 

 

SILICA GEL USES:

Silica Gel (silicon dioxide) has uses in many industries, especially those that perform large scale purifications for high purity products. Powdered silica gel can be used for the separation of small molecules, peptides and botanical extracts. Silica gel is mainly used to remove impurities from reactions that take place in organic solvents.

 

SILICA GEL, SILICON DIOXIDE (CAS No. 112926-00-8)

 Recommended Product

  • Chromatocel S-060 (230 x 400 mesh)

 

S= Silica Gel 

  

SILICA GEL USES - CHROMATOGRAPHY:
A variety of solid phase materials can be used in chromatography. Silica gel is often used because of its highly polar nature. Optimized particle size, surface area, pH, and purity make silica gel particularly effective for separation of small molecules, peptides, lipids, alkaloids, botanical extracts and a wide variety of other materials.

 

 

BATCH EXTRACTIONS AND DECOLORIZATION:

The Chromatocel S series of products not only have applications in chromatography, they also have particle size distributions that make them ideal candidates for batch extractions or decolorizing.

COMMON SEPARATION TECHNOLOGIES:
There are multiple separation techniques that utilize silica gel:  

Decolorizing, Batch Extractions, Liquid Chromatography, High Performance Liquid Chromatography, Flash Chromatography, and Thin Layer Chromatography.

QUALITY CHROMATOGRAPHIC SILICA GELS PROVIDE:
Reproducible separations:
Tight controls over process parameters enable Porocel to deliver products with low batch to batch variability.

High quality products:
High quality silica gel products protect users from introduction of outside contaminants.  Quality assurance systems and qualified cleaning processes maintain the purity of the silica gels allowing for cleaner separations and reduced washing steps.

 

Desirable particle size distributions:
Low fine content allows for efficient separations with reduced band tailing. The lowering of fines in high quality chromatographic silica gel also reduces process back pressures and can prevent premature filling during column packing.
