Microsorb™ Cyano, a cyanopropylsilane-covered silica, is unique in that it spans both the normal and reversed phase separation modes. When used with aqueous organic mobile phases, compounds elute in an order typical of reversed phase, with polar compounds eluting quickly and hydrophobic compounds being more retained.

Supplier: Restek

These cartridges are made of glass fiber disks embedded with C18 or C8 bonded silica. These hydrophobic (nonpolar) silica-based adsorbents are ideal to extract hydrophobic analytes from polar matrices, such as water (e.g., pesticides from water).

ZORBAX® Extend-C18 columns have high efficiency and a long life at high pH upto pH 11,5 with more effieincy and better peak shape than polymer-based columns.

Supplier: Agilent

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.
