pk20 Envicarb/LC-NH2/Si SPE Tubes 20mL, bed C 600 mg (Supelclean LC-Si), bed A 500 mg (Carbopack B 120/400), bed B 400 mg (Supelclean LC-NH2), volume 20 mL, pkg of 20 ea

The Supelclean ENVI-Carb/LC-NH2/Si SPE cartridge combines three separate sorbent layers of graphitised carbon, Supelclean LC-NH2 and Supelclean LC-Si. The ENVI-Carb layer binds pigments and other planar matrix components, while the aminopropyl phase retains fatty acids, organic acids and polar co-extractives and the unmodified silica provides additional normal-phase adsorption. Supelclean ENVI-Carb/LC-NH2/Si is used for particularly extensive cleanup of complex food and beverage extracts prior to chromatographic residue analysis.

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.
