Description générale

Retention Mechanism: Reversed-phase and anion-exchange
Sample Matrix Compatibility: Organic or aqueous solutions

  • Dual layer SPE tube that contains both Supelclean ENVI-Carb (upper layer) & LC-NH2 (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 LC-NH2 is an aminopropyl phase that retains fatty acids, organic acids, and some polar pigments and sugars common in food matrices

Solid Phase Extraction: Ion Exchange Methodology

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.

Solid Phase Extraction: Reversed-Phase Methodology

Protocoles

Solid Phase Extraction: Normal Phase Methodology

Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
