Supelclean™ LC-NH2 SPE Tube, bed wt. 500 mg, volume 3 mL, pk of 54

The Supelclean LC‑NH2 SPE cartridge uses an aminopropyl modification on silica. Supelclean LC‑NH2 can be used both as a polar normal‑phase sorbent and as a weak anion exchanger, thus offering a combination of adsorption and pH‑dependent ionic retention. Typical applications of Supelclean LC‑NH2 are work‑up of sugars, nucleotides, nucleosides, organic acids, fatty acids and pesticide extracts.

Features and Benefits

• Wide selection of different SPE selectivities
• Silica, polymer, carbon, and adsorbent materials
• Solutions for extraction, enrichment, and matrix cleanup
• Single-bed, mixed-bed, and multilayer cartridges available
• For food, environmental, pharmaceutical, and bioanalytical applications

Additional Information

Supelclean does not refer to a single base matrix, but rather to a comprehensive family of SPE products with different retention mechanisms. Conventional LC phases are primarily based on fully porous silica and include reversed-phase, normal-phase, and ion-exchange modifications. The ENVI products complement acid-washed silica materials, cross-linked polymer adsorbents, and various carbon adsorbents. Alumina, Florisil, activated carbon, and zirconium-based materials expand the selection with distinct adsorption and matrix cleanup properties. Multilayer cartridges combine multiple sorbents in a defined sequence. Conditioning, sample pH, solvents, and elution conditions must therefore always be tailored to the specific Supelclean material and the target analytes.
