Reversed Phase C18A SPE Cartridges

Function Group: C18
Particle size: 40 – 75μm
Average pore size: 60Å


Description of Reversed Phase C18A Solid Phase Extraction(SPE) Cartridges

The C18A solid phase extraction (SPE) cartridge uses octadecyl silica as a filler to extract non-polar compounds from aqueous solution by hydrophobic interaction. The fully covered surface is hydrophilically modified to allow the stationary phase to be easily wetted by water, to maintain the carbon chain upright in the aqueous mobile phase, and to improve the water resistance of the silica matrix.
