SPE columns, CHROMABOND SiOH, 45 µm, 6 mL/1000 mg 140-061-621 1-Ethenylpyrrolidin-2-one (1-Vinylpyrrolidin-2-one)Unmodified, 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
