Supelclean™ ENVI-Carb™ II/PSA SPE Tube, bed B 300 mg (Supelclean™ PSA SPE), bed A 500 mg (Supelclean™ Envi-Carb-II SPE), volume 6 mL, pk of 30

The Supelclean ENVI-Carb-II/PSA SPE cartridge combines an upper layer of graphitised ENVI-Carb-II with a lower PSA layer. Supelclean ENVI-Carb-II/PSA retains chlorophyll, carotenoids and sterols on the carbon, while PSA removes fatty acids, organic acids, polar pigments and partially sugars. Supelclean ENVI-Carb-II/PSA is intended for cleanup of food and agricultural samples prior to multi-residue determination of pesticides by GC-MS or LC-MS.

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.
