SMT SAM BOD – Bulk C18 Resin

C18 resins for separation of hydrophobic molecules from aqueous and biological samples

Part Number:  N/A Category: Tags: , , ,


SMT manufactures the most reliable silica based octadecyl (C18) resins available in the market today. This advanced new bulk media is very stable at a wide pH range and high temperatures. SMT utilizes a proprietary bonding scheme that allows the resulting bonded phases to perform separation of basic, neutral and acidic compounds under aggressive pH conditions. Separation of most basic solutes is often possible without TFA or other mobile phase additives. BOD C18 packing materials are silica based.

Unique features include:

  • Extremely high coverage
  • Wide range of pH stability (1 to 12)
  • Highest levels of consistency and reproducibility
  • High throughput – No carry over of any analytes
  • Low back pressure
  • Can be packed in columns (capillary, stainless steel, peek and glass)
  • Analytical, solid phase extraction and process scale purifications

We manufacture a variety of silica based bulk packing materials for analytical to large-scale purifications. SMT offers a range of bulk C18 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.
