AQ C18 series using a polar chemical group to modify the spherical C18 surface and enhance the retention for polar substance. The bonded chemical group also make RP surface more hydrophilic, and provide good recovery for both polar and non-polar compounds, especially for water samples.
Cleanert S C18 (End-capped)
Cleanert S C18 columns and plates are packed with octadecylsilane bonded silica sorbents. The sorbent is double end-capped and has a high bonding density (%C > 17).
Cleanert S C18-N (Non-end-capped)
Cleanert S C18-N is a type of C18 sorbent bonded to silica without end-capping modification, providing extra silanol residuals around the root of alkyl chain on silica surface.
Cleanert S C8 (Octyl)
Cleanert S C8 is successfully used for the extraction of both water-soluble and fat-soluble vitamins from serum, as well as the desalting of biological macromolecules.
Cleanert CN (Cyanopropyl)
Cleanert CN(Cyano) SPE is silica based sorbent bonded with cyanopropyl functional groups. This polar sorbent exhibits both polar and non-polar interactions.
