Ion-Exchange Amino (NH2) SPE Cartridges

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 Ion-Exchange Amino (NH2) SPE Cartridges

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

Parameters of Amino (NH2) SPE Cartridges

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)
