SMT manufactures ultra-stable CN or CyanoPropyl (CP) bulk packings for normal and reversed-phase chromatographic separation modes. These bulk packings have some special characteristics: When used in normal phase mode, with relatively nonpolar solvents, CN-stationary phase can separate many polar compounds just like silica. When used in reversed-phase mode, with relatively polar solvents, CN-stationary phase offers complimentary selectivity that may be unattainable with traditional reversed-phase packings such as C18 and C8.
- 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 cyanopropyl (CN) 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.
Are you looking for bulk packings with custom specifications (pore size, particle size and/or quantity) not available on this site? Please contact us as we can manufacture the exact bulk media you need.
