جاذب SPE-SAX

توضیحات

SAX is a silica-based strong anion exchanger. Its quaternary ammonium ligand is always positively charged and engenders very strong anion exchange capacity. SAX is able to extract acidic compounds such as carboxylic acids.

Features:

  • Very strong anion exchange interaction with acidic compounds
  • Capable of retaining compounds that elute from weak anion exchange sorbents
  • Simple retention mechanism, with minimal secondary interactions

Specifications:

Surface area: 510 m 2/g
Particle size: 40 – 75 μm
Pore size: 70 Å

Applications:

  • Removal of negatively charged substances such as organic acids, nucleotides, sulfonic acids and inorganic anions from samples
  • Determination of hormones in meat
  • Determination of sulfonylurea herbicides in soil, vegetables and cereals
