Solid Phase Extraction
Waters Corp Sep-Pak Silica Plus Light Cartridge, 120 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Polar sorbent, used primarily to adsorb analytes from non polar solvents like hydrocarbons, chloro- or flouro-substituted hydrocarbons or less polar esters and ethers.
Waters Corp Waters Sep-Pak Accell Plus QMA Vac Cartridge, 3 mL, 37 to 55 μm
Sep-Pak Accell Plus QMA Vac cartridges are silica-based, hydrophilic, strong anion-exchangers designed for the extraction of anionic analytes from aqueous and non-aqueous solutions. Their large pore size (300Å) allows isolation of larger molecules, and they are suitable for use with vacuum manifolds and automated SPE instruments.
- Silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å).
- Designed for extraction of anionic analytes in aqueous and non-aqueous solutions.
- Large pore size is ideal for isolating larger molecules such as anionic proteins (immunoglobulins and enzymes).
- Applications include isolating phenolic compounds and removing acidic pigments in wine, fruit juices, and food extracts.
- Syringe-barrel-type cartridges designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Waters Sep-Pak C18 Plus Short Cartridge, 360 mg Sorbent, 55–105 μm
This solid phase extraction cartridge with 360 mg of C18 sorbent (55–105 μm particle size) is designed for sample preparation. It adsorbs analytes of even weak hydrophobicity from aqueous solutions, functioning similarly to reversed-phase HPLC columns.
- Silica-based bonded phase with strong hydrophobicity.
- Suitable for robotic and manual applications.
- Allows flow direction reversal for trace enrichment.
- Reduces costs by consuming less solvent and reagent.
- Increases recoveries through minimum sample transfer.
- Enhances safety by easing disposal and reducing toxic exposure.
- Improves accuracy, preventing cross-contamination.
- Eliminates emulsion issues with simplified sample handling.
- Designed for retaining non-polar and moderately polar compounds.
- Compatible with various solvents like methanol, acetonitrile, and aqueous solutions.

Waters Corp Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Carbonate Plus Light cartridges contain a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. These cartridges are used for extraction of anionic analytes in aqueous and non-aqueous solutions when the chloride counter-ion in the standard Sep-Pak Accell Plus QMA cartridges interferes with the analysis. These Light-style cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
Waters Corp Sep-Pak Aminopropyl (NH2) Classic Cartridge, 360 mg, 55 to 105 μm
These Sep-Pak Aminopropyl (NH2) Classic cartridges provide a moderately polar, silica-based bonded phase with a weakly basic surface. They function as polar sorbents or weak anion exchangers (below pH 8), ideal for extracting various analytes including phenols, saccharides, drugs, and metabolites.
- Moderately polar, silica-based bonded phase with a weakly basic surface
- Functions as a polar sorbent or weak anion exchanger (below pH 8)
- Suitable for extracting phenols, phenolic pigments, petroleum fractionation, saccharides, drugs, and metabolites
- Designed for positive displacement with Luer-tip syringes
- Attachable to vacuum-assisted flow devices with a male/male adaptor
