Mixed Mode Octyl(C8)/SCX SPE Cartridges

Description of Mixed Mode C8/SCX SPE Cartridge

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 Cartridge

• 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.

Parameters

• Specific surface area: 510 m²/g;
• Average particle size: 40-75 μm;
• Average pore size: 70 Å.

Applications

C8/SCX mixed mode cartridge, Integrates the advantages of two packings, and can satisfy a wide range of application needs, including:

• Detection of drugs and metabolites in biological fluids, such as acetaminophen
• Detection of drug abuse
