Mixed Mode C8/SCX 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 SPE cartridges, 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 C8/SCX 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
