Descrição geral
Sample Matrix Compatibility: Organic or aqueous solutions
- Tri-layer SPE tube that contains Supelclean ENVI-Carb (upper layer), SAX (middle layer) & PSA (lower layer) SPE sorbents (separated by PE frit)
- Developed to offer superior clean up when conducting multi-residue pesticide analysis from food (e.g. agricultural products, meats, etc.).
- ENVI-carb has a strong affinity towards planar molecules, and can isolate/remove pigments (e.g., chlorophyll and carotinoids) and sterols commonly present in foods and natural products
- Supelclean PSA has a strong affinity and high capacity for fatty acids, organic acids, and some polar pigments and sugars
- Supelclean SAX offers additional ion-exchange exchange capacity for removing matrix components that may induce ion-suppression or enhancement during GC analysis.

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.
SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.
Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
Protocolos
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
