General description

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

Application

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.
