SiliaSphere as a Silica Matrix
For over 18 years, SiliCycle has been dedicated to silica gel manufacturing and we have achieved a strong know-how and expertise in this field. Furthermore, to support the increasing demand on our spherical silicas, we have developed an optimized and highly controlled large-scale production process for all of our SiliaSphere products without decreasing the quality of the silica.
Particle shape, pore and particle size distributions, silica gel purity, and surface properties, all have their influence on chromatographic performance. Therefore, in order to develop the most efficient process, all previously mentioned parameters need to be evaluated and optimized to ensure batch-to-batch reproducibility.
SiliaSphere is manufactured from an organic form of silicon (alkoxydes). This ensures very low metal content as the starting material is purified by distillation. Deionized water is used to hydrolyze the silicon alkoxydes. Careful monitoring and control of the parameters that induce precipitation afford spherical silica gels with the desired characteristics. SiliaSphere products are characterized by a very low metal content and exceptional stability even at extreme pHs. Furthermore, our manufacturing process ensures quality and reproducibility in pore size, surface area and particle sizes and morphology for all SiliaSphere products.
Perfectly Spherical Particle Shape
The perfectly spherical shape of SiliaSphere silicas, combined to their smooth surfaces free of any cracks, cavities and fines make them the packing of choice for chromatography. The SiliaSphere sphericity exceeds or compares favorably to well-known brands in spherical silica gel as demonstrated by the scanning electron microscope (SEM) picture.
