Supelclean™ LC-Si SPE Tube, glass hardware, PTFE frit, bed wt. 500 mg, volume 6 mL, pk of 30

The Supelclean LC‑Si SPE cartridge is packed with unmodified, fully porous silica. The polar silanol groups give Supelclean LC‑Si pronounced normal‑phase and adsorption selectivity for polar compounds from non‑polar sample solutions. Supelclean LC‑Si is used, for example, for fractionation of lipid classes, purification of oil extracts and for work‑up of sterols, pesticides and oxygen‑ or nitrogen‑containing compounds.

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.
