Aminopropyl AP (NH2) Columns

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:

• Normal-Phase
• Weakly Anion Exchange
• Reversed-Phase

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:

• Improved separation of polar solutes; excellent sample recovery; high loading capability
• High reproducibility of bonded ligand resulting in consistent separation
• Increased longevity provided through “Total Coverage”

SMT offers two types of columns:

• Aminopropyl (AP-series)
• Aminopropyl Methyl (APM-series)
