C18A SPE Cartridge
Extracting non-polar compounds
Finetech® C18A sorbent is composed of octadecyl-bounded silica gel particles and retains non-polar compounds by hydrophobic interactions.
Hydrophilic surface modification makes C18A wettable and prevents its carbon chains from collapsing in aqueous solution. Due to its compatibility with aqueous mobile phases, even pure water can be used, and silica particles are more stable.
