Mechanism of action: NH2
Particle size: 40-75μm
Average pore size: 100 Å

Availability: In Stock


NH2 SPE Cartridges


NH2 (amino) bonded phase has strong polar adsorption in non-polar organic solvents, with weak anion exchange retention. NH2 SPE cartridge‘s effect with anions is weaker than SAX SPE cartridge.
NH2 excels in a variety of sample matrices for use in food, environmental, pharmaceutical, and medical applications.

Characteristics of Anion-Exchange Amino (NH2) SPE Cartridge

  • Has dual retention of normal phase and anion exchange;
  • Handles complex sample matrices such as biological fluids.

Parameters of Amino (NH2) SPE Cartridge

  • Carbon content: 4.5%;
  • Specific surface area: 200 m²/g;
  • Average particle size: 40-75 μm;
  • Average pore size: 100 Å.


  • Remove strong anions (such as sulfonates) from aqueous solutions;
  • Separation of organic acids, lipids, alcohols, sugars, steroids, and cholesterol;
  • Drugs and their metabolites (antagonists, salicylic acid) in biological matrices (urine, blood);
  • Macrolide insecticides in food and water;
  • Detection of organic acids in air pollutants (removal of esters).
