Supelclean™ ENVI-Carb™ Plus SPE Tube, Reversible Tube, bed wt. 400 mg, volume 1 mL, pk of 30

The reversible Supelclean ENVI-Carb Plus SPE cartridge contains an amorphous, spherical carbon molecular sieve. Unlike classical graphitised carbon, Supelclean ENVI-Carb Plus is designed for extraction of very polar organic compounds from large water sample volumes; for elution the cartridge is flowed through in reverse. Supelclean ENVI-Carb Plus is suitable among others for 1,4-dioxane, acrylamide, acephate, oxamyl and phenol; in vacuum operation appropriate male and female Luer fittings as well as an empty collection tube are required.

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.
