Waters, WAT023525, Sep-Pak Accell Plus QMA Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk

Sep-Pak Accell Plus QMA Plus Light is a strong anion-exchange solid-phase extraction cartridge for isolating negatively charged analytes from prepared samples. Each cartridge contains 130 mg of hydrophilic silica-based QMA sorbent with 37–55 µm particles and 300 Å pores. The Plus Light format has a low hold-up volume of approximately 0.4 mL, helping reduce unnecessary dilution when collecting retained fractions. It is useful for sample cleanup and fractionation of anionic species, including larger negatively charged molecules under suitable loading and elution conditions. Sorbent capacity and analyte recovery depend on pH, ionic strength and sample composition, so loading and elution conditions should be optimized for the target mixture. Condition the cartridge with compatible solvents before loading, avoid excessive particulate material and collect fractions in correctly labeled vessels. This format is supplied as 50 cartridges and is not the same as a QMA Carbonate cartridge. Confirm the required counterion form and extraction method before changing cartridge types.
