Reversed Phase C18A SPE Cartridges

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


Reversed Phase C18A SPE Cartridges


The C18A SPE cartridge uses octadecyl silica as a filler to extract non-polar compounds from an 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.
