일반 설명

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

  • Polymerically bonded, ethylenediamine-N-propyl phase that contains both primary and secondary amines
  • A weak anion exchanger with a pKa of 10.1 and 10.9
  • Similar to aminopropyl SPE phases (NH2) in terms of selectivity, but has a much higher capacity due to presence of secondary amine (0.98-1.05 meq/g)
  • Strong affinity and high capacity for removing fatty acids, organic acids, and some polar pigments and sugars when conducting multi-residue pesticide analysis in foods
  • Has been shown to significantly reduce matrix-enhancement effects encountered during the GC analysis of food products
  • Tested for superior cleanliness using GC-FID and GC-MS
  • Bidentate nature of ligand allows for chelation

애플리케이션

Supelclean PSA SPE Bulk Packing may be used as a sorbent in the solid-phase dispersive extraction followed by single flow injection multi-commuted system/solid-surface fluorescence spectroscopic analysis of diphenylamine in apples and pears.

Rapid determination of diphenylamine residues in apples and pears with a single multicommuted fluorometric optosensor

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.

프로토콜

Extraction and Analysis of Agricultural Pesticides from Oranges Using the “QuEChERS” Method

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.
