SPE column, CHROMABOND SiOH, 45 µm, 45 mL/5000 mg

Description

Non-modified, weakly acidic silica gels, very polar. Adsorbs moisture from the air, so it should be well sealed and, if necessary, dried before use. Due to its high affinity to polar compounds, it should not be conditioned with polar (e.g. methanol) or aqueous solvents.
