General description
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

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.
Protocols
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
