Mixed Mode C8/SAX SPE Cartridges
Octyl(C8)/SAX SPE Cartridges are hybrid which can take advantage of the two cartridges’ respective characteristics. This mixed mode cartridge has double retention ability since the functional group of the cartridge is made up of a proportionally bonded octyl and a quaternary amine group. The former provides moderate hydrophobic interaction and the latter provides strong anion exchange.
Hawach Mixed mode extraction cartridge can be applied in samples over-adsorbed by C8 or C18 SPE cartridges, or too retentive to SAX.
They are perfectly suitable for the treatment of complex matrix samples such as blood and urine
Characteristics of Mixed Mode Octyl(C8)/SAX 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.
Specific surface area: 510 m²/g
Average particle size: 40 – 75μm
Average pore size: 70 Å
Applications of Mixed Mode Octyl(C8)/SAX SPE Cartridges
Detection of drugs like THC, can be used in drug abuse.
Detection of metabolites in biological fluids (blood and urine), such as barbiturates and aryl benzoic acids.
