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.

Phthalates, plastic-derived contaminants, are of increasing global concern. This study quantified phthalates in seabirds collected across >1700 km of the Aleutian Islands, Alaska, and contributes to a body of knowledge on plastic contaminants in marine wildlife. We measured six phthalate congeners

Protocols

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.

Related Content

Solid phase extraction (SPE) is a technique used for rapid, selective sample preparation and purification prior to chromatographic analysis (e.g. HPLC, GC, TLC). SPE is used to exchange sample matrices, concentrate analytes, and remove interferences and contaminants to improve data and protect the analytical column.
