SPE columns, CHROMABOND SiOH, 45 µm, 6 mL/2000 mg OPTIMA 1701 n-Nonyl n-undecyl phthalateUnmodified, 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 Macherey Nagel Chromatography Catalogue
