Food & Beverage Traceability
Silica gels are used in chromatographic separations for analytical quality control of food as well as in the manufacturing of various food ingredients. Very fine particle-size silica gels are used as filter aids and clearing agents mostly in the beverage industry.
Zeochem offers a suite of product lines to support specific industrial needs.
- ZEOprep: Irregular silica is one of the most widely used chromatography sorbents in the world. It is available in a wide range of pore and particle sizes with modifications from small to multi-ton quantities to meet application, performance and economic requirements.
- ZEObeads: Microbeads offer better chromatographic performance compared with irregular ZEOprep products but are still economically priced.
- ZEOsphere: Spherical silica is for normal phase and reversed-phase applications. Available products include classical reversed phases (e.g., C18, C8, C4, etc.) and ZEOsphere DRP Mixed-Mode silica for separation and purification of charged compounds. ZEOsphere silica is available in various pore and particle sizes as well as multiple modifications.
All our products are produced at ISO-9001 certified facilities. Strict quality control from raw material to finished product guarantees optimized chromatographic performance. Each step in the production process is closely monitored to minimize product variation and to secure high lot-to-lot finished product reproducibility.
