SPE columns, CHROMABOND SiOH, 45 µm, 6 mL/500 mg [35071][MICROLAB] Chemical Form in Solution: Hf(F)6-2Unmodified, weakly acidic silica, 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. Technical Data Downloads Mode Normal phase (NP) Particle type Fully porous particles (FPP) Surface chemistry Unmodified silica gel (SiOH) Endcapped No pH stability 2.
