Copure C8/SCX SPE Cartridges

Copure C8/SCX is composed of silica gel bonded with octyl and phenylsulfonic acid groups at a specific ratio. It’s a mixed-mode sorbent with two retention mechanisms: octyl groups provide moderately hydrophobic interactions, phenylsulfonic acid groups provide strong cation exchange

C8/SCX will be a better choice if very strong absorption in C18, C8 or SCX packing results in difficult elution of some analytes.

Available in different formats.

• Moderate retention, avoiding extremely strong adsorption of some compounds
• Ideal for complicated samples such as blood and urine

Surface area: 510 m ²/g
Particle size: 40 - 75 μm
Pore size: 70 Å

• Determination of drugs and their metabolites in biological fluids
• Determination of drugs of abuse such as cocaine, acetylcodeine, morphine and ketamine
