NH2 Solid Phase Extraction(SPE) Column
NH2 (aminopropyl) bonded phase has strong polar adsorption and weak anion exchange retention in non-polar organic solvents.
NH2 SPE column shows excellent performance in a variety of sample matrices, and can be used in food, environment, pharmaceutical and medical fields.
It has dual retention function of normal phase and anion exchange;
It can handle complex sample matrix such as biological liquid.
Removal of strong anions (such as sulfonate) from aqueous solution;
Separation of organic acids, lipids, alcohols, sugars, steroids and cholesterol and other substances;
Drugs and their metabolites (epinephrine antagonists, salicylic acid) in biological matrix (urine, blood);
Macrolide insecticides in food and water;
Detection of organic acids in air pollutants (removal of esters).
