Supelclean™ ENVI-Carb™-II/SAX/PSA SPE Tube, bed A 500 mg (Supelclean™ ENVI-Carb-II SPE), bed C 500 mg (Supelclean™ PSA SPE), bed B 500 mg (Supelclean™ LC-SAX SPE), volume 12 mL, pk of 20

The three-layer Supelclean ENVI-Carb-II/SAX/PSA SPE cartridge combines graphitised carbon, a strong anion exchanger and PSA. Supelclean ENVI-Carb-II/SAX/PSA simultaneously removes pigments and sterols, strongly acidic matrix components as well as fatty acids, organic acids and other polar interferences. This makes Supelclean ENVI-Carb-II/SAX/PSA suitable for particularly demanding food and plant extracts prior to pesticide 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.
