ZEOprep, ZEObeads and ZEOsphere excel in their efficiency to create the best filtration, separation and purification solutions for a large variety of compounds and/or industries.
Alkyl-bonded silica for reversed-phase chromatography is a robust and reliable packing material, widely used in industrial separations as well as in flash chromatography.
Alkyl-bonded silica with shorter chain length and slightly reduced hydrophobicity which is used in reversed-phase chromatography. The shorter alkyl length allows for better interaction between stationary phase and the target compound.
Cyan-bonded silica is more polar than C18/8 bonding but is mostly used in reversed-phase chromatography for polar compounds and for a broader range of pH environment.
Diol-bonded silica, more polar than C18/C8 types. Used in reversed- as well as in normal-phase chromatography, it is the product of choice for acid-sensitive compounds.
Amine-bonded silica is mostly used in normal-phase chromatography and serves as an efficient metal scavenger in batch applications, best for removing metals such as nickel.
Primary, secondary amine-bonded silica and is more polar than C18/C8 phases. It is used in reversed-phase as well in normal-phase chromatography.
Silica-bonded for anion exchange chromatography.
Thiol-bonded silica most efficiently serves as a metal scavenger, but it is also used as a means to remove palladium in batch applications.
Alkyl-bonded silica with 90 angstrom pore size that has proved to be a robust packing material in particular for flash cartridges.
Alkyl-bonded silica with 90 angstrom pore size and a larger particle size distribution which provides a higher flow rate under low-pressure applications.
