설명

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
