Mixed Mode Octyl(C8)/SAX SPE Cartridges
Description
Description of Mixed Mode Octyl(C8)/Strong Anion Exchange(SAX) Solid Phase Extraction(SPE) Cartridges
The functional group of the C8(octyl)/strong anion exchange(SAX) solid phase extraction(SPE) cartridge consists of a proportionally bonded octyl and quaternary amine group with dual retention: the octyl group provides a moderate hydrophobic effect and the quaternary amine group provides a strong anion exchange.
For samples that are over-adsorbed by C18 and C8, and that are too retentive to SAX, the C8/SAX mixed mode extraction cartridge can be used.
Characteristics of Mixed Mode Octyl(C8)/Strong Anion Exchange(SAX) Solid Phase Extraction(SPE) Cartridges
Medium retention capacity to solve the problem that individual target compounds are difficult to elute.
Suitable for processing complex matrix samples such as blood and urine.
