| 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 |
