C8/SCX SPE Cartridge

Extracting basic drugs in biological fluids

Finetech® 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 adsorption in C18, C8 or SCX packing results in difficult elution of some analytes.
