Description

Mixed Mode C8 SAX SPE Cartridges

Function group: C8/strong anion exchange;
Retention Mechanism: reversed phase/anion exchange selectivity

Description of Mixed-Mode Solid Phase Extraction Cartridge

The functional group of Hawach C8/SAX solid phase extraction columns is mixed SPE cartridges which consist of proportionally bonded octyl and quaternary amine groups with double retention: octyl provides moderate hydrophobicity and quaternary amine provides strong Anion exchange. For samples that are difficult to elute due to excessive adsorption of C18 and C8 and excessive SAX retention capacity, a C8/SAX mixed mode solid phase extraction cartridge can be used. For samples that are over-adsorbed by C18 and C8, and that are too retentive to SAX, the C8/SAX mixed-mode extraction column can be used.

Features of Mixed Mode C8/SAX SPE Cartridge

Particle size: 40-75μm
Average pore size: 70 Å
Function group: C8/strong anion exchange.
Retention Mechanism: reversed-phase/anion exchange selectivity.
Medium retention capacity to solve the problem that individual target compounds are difficult to elute.
