SMT manufactures very stable aminopropyl (NH2) columns. SMT Amino (NH2) bulk packings are often recommended for the separation of polar compounds and can be used in three separation modes:
In normal phase mode, the bulk packings can be used to separate polar compounds such as substituted anilines, phenols, and chlorinated pesticides. In reversed-phase mode, separation of organic acids and anions is possible with the addition of common buffers. Other applications include reversed-phase separation of carbohydrates in food and beverages. Unique features include:
SMT offers two types of columns:

SMT SAM AP – Normal Phase Amino (NH2) Column
AP Amino (NH2) columns for separation of strong anions from aqueous samples. Can be used in the normal phase and HILIC mode. Provides different normal-phase selectivity than bare silica, substantially for aromatics.
