Ion-Exchange Amino (NH2) SPE Cartridge

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.

Applications

• 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).

Relevant Standards
