Description

Endcapped. 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.

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
