Gelest, Inc offers a range of materials that provide the chemical variation for a wide variety of chromatography and related applications. These range from the long-chain aliphatic-substituted silanes for reversed phase chromatography, to organofunctional organosilanes, including amino, mercapto, epoxy and other functionalities that are covalently bonded through a carbon chain to the silicon group, and long-chain functional organosilanes. These latter include long chain organosilanes containing an amino, aldehyde, ester, or cyano group on the w-position 11 carbons removed from the silicon moiety. Gelest also supplies various dipodal silanes, which find use in the preparation of specialty silicas in addition to providing excellent hydrophobicity to surfaces.
