OL C8 Columns

SMT offers three different C8 phases of varying carbon loads for optimal selectivity:
 
OL series
SMT SAM-C8 phase with the lowest functional ligand coverage confirmed with carbon analysis results of 6% carbon load.  In these series, the proportional ratio of the functional ligand, octyl or C8 molecule , mixed with the proprietary spacer molecule,  is reduced.  The result is a packing material with maximum coverage but much lower functional ligand density.  Low density C8 packing material ensures faster mass transfer of solutes during separation. These phases have low hydrophobicity.  The spacer molecules protect the substrate from aggressive pH conditions and impact unique selectivity compared with other C8 phases. 
 
O series
SMT SAM-C8 phase with the highest functional ligand coverage confirmed with carbon analysis results of 12% carbon load. In these series, a very high density of the functional ligand, octyl molecule or C8, is achieved through meticulous mixture of the C8 with proprietary spacer molecules to ensure maximum coverage. These phases are very hydrophobic and are designed to tolerate usage in mildly aggressive pH conditions and high temperatures. SMT SAM-C8 columns are designed to withstand a pH range of 1-10.  The columns are generally stable up to 50% better than other competitors used under similar conditions.
 
Elite-C8 series  
SMT SAM-C8 phases with the intermediate functional ligand coverage confirmed with carbon analysis results of 10% carbon load. In these series, the density of the functional ligand, octyl molecule or C8, is moderated with the proprietary spacer molecule to ensure maximum coverage. These phases are moderately hydrophobic; nevertheless, designed to tolerate usage in very aggressive pH conditions and high temperatures.

  • SMT SAM OL C8 – Reversed-Phase C8 Column

    SMT manufactures OL C8 columns, the most commonly used column type after C18. These durable columns are very low in carbon load and are used in rapid analysis of hydrophobic compounds.

  • SMT SAM OL C8 – Guard Column

    C8 Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
