Unmodified silica phase for SPEUnmodified, weakly acidic silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, very polar, adsorbs humidity from air, for this reason it should be kept well closed and if necessary dried before use due to its high affinity for polar compounds it should not be conditioned with polar (e.g. methanol) or water-containing solvents.Recommended applications: aflatoxins, chloramphenicol, pesticides, steroids, vitamins.

Octyl modified silica phase for SPE, not endcappedBase material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8. Octyl phase, not endcapped, carbon content 8%, similar to C18, however slightly more polar. Secondary interactions with polar compounds are more pronounced due to shorter alkyl chains.Recommended applications: pesticides, PCBs.
