Application:

  • Chromatographic Separation: Silica gel is widely used as a stationary phase in chromatography for the separation of various chemical compounds. Innovations in silica gel modification, such as pentabromobenzyl group-modified silica gel, have enhanced the separation efficiency for metabolites like nicotinamide. This application is critical for pharmaceutical analysis and metabolomics studies, providing high precision and accuracy in the quantification of biologically relevant molecules (Ozaki et al., Analytical Biochemistry, 2022 ).

  • Environmental Pollutant Detection: Silica gel is used to create molecularly imprinted polymers (MIPs) that selectively recognize and bind environmental pollutants. A notable application involves the embedding of quantum dots in molecularly imprinted silica gel to detect aminoimidazo-azaarenes (AIAs) in food samples. This method offers high selectivity and sensitivity, making it a powerful tool for food safety and environmental monitoring (Qiao et al., Current Analytical Chemistry, 2021 ).
General description: Silica gel is a rigid 3D network of colloidal silica. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation leading to form uniform polymer particles with narrow particle size distribution and high bulk density. Silica gel is classified as below:
a. Aquagel - pores are filled with water
b. Xerogel - by the process of evaporation, aqueous phase in the pores are removed
c. Aerogel - solvent removed by supercritical extraction.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
