Waters Corp Sep-Pak Solid Phase Extraction, 46 mg Sorbent, 40 μm, 300 Å, 50/pk
These silica-based, hydrophilic, strong anion-exchanger cartridges feature a large pore size (300Å) and a carbonate counter-ion, ideal for extracting anionic analytes in aqueous and non-aqueous solutions. The “Light-style” design with reduced internal diameter optimizes recoveries and reduces solvent consumption by allowing elution of fractions in minimal volume.
