Supelclean™ LC-Alumina-N SPE Tube, bed wt. 1 g, volume 3 mL, pkg of 54 ea

The Supelclean LC-Alumina-N SPE cartridge is packed with neutral-conditioned aluminium oxide at approximately pH 6.5. Supelclean LC-Alumina-N adsorbs medium-polarity to polar compounds from non-aqueous samples without emphasising the strongly acidic or basic selectivity of the two other alumina variants. Supelclean LC-Alumina-N is suitable for general normal-phase cleanup steps, fractionation of organic mixtures and processing of pesticides, lipids and natural products.

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.
