Mixed Mode Octyl(C8)/SCX SPE Cartridges

Description of Mixed Mode Octyl(C8)/Sulfonic Acid Silica Gel(SCX) Solid Phase Extraction(SPE) Cartridges

The functional group of the C8/SCX (octyl/sulfonic acid silica gel) filler consists of a proportionally bonded octyl and sulfonic acid group with dual retention: the octyl group provides a moderate hydrophobic effect and the sulfonic acid group provides a strong cation exchange.
For samples that are over-adsorbed by C18 and C8, and that the SCX retention is too strong to cause elution difficulties, the C8/SCX mixed mode extraction cartridge can be used.

Features of Mixed Mode Octyl(C8)/Sulfonic Acid Silica Gel(SCX) Solid Phase Extraction(SPE) Cartridges

Medium retention capacity, solving the problem that individual target compounds are difficult to elute.
Suitable for processing complex matrix samples such as blood and urine
