Mixed Mode SPE Cartridge
1. Mixed Mode C8/SAX SPE Cartridge
The functional group of C8/SAX is composed of octyl and quaternary amine groups bonded in proportion, and has a dual retention effect: the octyl group provides a medium hydrophobic effect, and the quaternary amine group provides a strong anion exchange effect.
For samples that are difficult to elute due to excessive adsorption of C18 and C8 and excessive SAX retention capacity, C8/SAX mixed mode extraction cartridges can be used.
Features of mixed mode C8/SAX extraction cartridge:
Medium retention capacity to solve the problem of difficult elution of individual target compounds.
Suitable for the processing of complex matrix samples such as blood and urine.
Parameter:
Specific surface area: 510 m2/g.
Average particle size: 40-75 μm.
Average pore size: 70 Å.
Applications:
Detection of metabolites in biological fluids, such as barbiturates and aryl benzoic acids.
Detect abuse, such as THC.
2.Mixed Mode C8/SCX SPE Cartridge
The functional group of C8/SCX is composed of octyl and sulfonic acid groups bonded in proportion, and has a dual retention effect: the octyl group provides a medium hydrophobic effect, and the sulfonic acid group provides a strong cation exchange effect.
For samples that are difficult to elute due to excessive adsorption of C18 and C8 and excessive retention of SCX, a C8/SCX mixed mode extraction column can be used.
Features of Mixed Mode C8/SCX SPE Cartridge:
Medium retention capacity, to solve the problem of difficult elution of individual target compounds.
It is suitable for the processing of complex matrix samples such as blood and urine.
Parameter:
Specific surface area: 510 m2/g.
Average particle size: 40-75μm.
Average pore size: 70 Å.
Applications:
Detect drugs and metabolites in biological fluids, such as acetaminophen.
