Supelclean™ LC-18 SPE Tube, bed wt. 500 mg, volume 6 mL, pkg of 30 ea

The Supelclean LC‑18 SPE cartridge contains a monomerically bonded and endcapped octadecyl modification (also designated ODS, RP‑18, C18) on fully porous silica. In reversed‑phase SPE Supelclean LC‑18 retains non‑polar to mid‑polar compounds from aqueous samples. Supelclean LC‑18 is used, among other applications, for extraction of pharmaceuticals, pesticides, steroids, prostaglandins, fat‑soluble vitamins and other hydrophobic analytes.

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.
