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

애플리케이션

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.

고체상 추출법(SPE)은 크로마토그래피 분석(예: HPLC, GC, TLC)에 앞서 빠르고 선택적인 시료 전처리 및 정제에 사용되는 기법입니다. SPE는 데이터를 개선하고 분석용 컬럼을 보호하기 위하여 시료 매트릭스를 교환하고, 분석물을 농축하며, 간섭과 오염 물질을 제거하는 데 사용됩니다.

Solid phase extraction purifies samples for chromatographic analysis, improving data quality and protecting analytical columns.
