O C8 Columns

SMT offers three different C8 phases of varying carbon loads for optimal selectivity:   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.   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.

Elite-C8 series   SMT SAM C8 phase 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 O C8 – Reversed-Phase C8 Column

  SMT manufactures O C8 columns for all general-purpose reversed-phase applications. These columns provide excellent peak shape and efficiency compared to competitive columns. C8 is generally less retentive than C18.

  SMT SAM O 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.
