SMT manufactures very stable Amino (NH2) bulk packings. SMT NH2 bulk packings are often recommended for the separation of polar compounds and can be used in three separation modes:
- Weakly Anion Exchange
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:
- Highest levels of Consistency and Reproducibility
- High throughput – No carry over of any analytes
- Low back pressure
- Perfect for Solid Phase Extraction and Process Scale purifications
- Ideal for applications in flash cartridges
We manufacture a variety of silica based bulk packing materials for analytical to large-scale purifications. SMT offers a range of bulk aminopropyl (NH₂) packings resins for those who prefer to pack their own column hardware. Samples from different lots can be purchased for method and process validation.
Silica gel and Bulk Packing materials for process scale applications are available in various particle sizes and pore sizes: 10, 20, 35, 60µm and 60, 100, 150 and 300Å are stock sizes.
