SPE glass columns, CHROMABOND SiOH, 45 µm, 3 mL/500 mg 5190-1599 Semi-quantitative test strips for theUnmodified, 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.
