Sielc HPLC Columns
Sielc PRIMSEP HPLC Columns:
Primesep A columns are reversed-phase analysis columns with embedded strongly acidic functional groups. These groups improve the retention of weak basic compounds by cation exchange mechanisms. All mobile phases are compatible with LC-MS as well as with preparative chromatography.
All SIELC Primsep A HPLC columns are available in different versions:

Primesep AB is also a reversed phase column with embedded acidic and basic functional groups. These groups improve the retention of strongly acidic and strongly basic compounds by ion exchange mechanisms and thus allows the separation of these. All mobile phases are compatible with LC-MS as well as with preparative chromatography.

Sielc OBELISC HPLC-Columns:
Obelisc ™ HPLC columns are the latest innovative columns from SIELC Technologies. Obelisc columns are the first commercially available columns with Liquid Separation Cell Technology (LiSCTM). The LiSC technology is based on a chemical modification of the silica gel pores, which creates a liquid separation cell with its own charge properties, ionic strength and hydrophobic properties. Like a living cell, which is in equilibrium with the external environment, liquid separation cells exist in a constant equilibrium with the mobile phase.
Sielc Obelisc R HPLC Column
Obelisc R is a reversed-phase analysis column, with non-polar hydrophobic side chains bounded to silica gel or a polymer. By additional ionic groups on a long hydrophobic chain, Obelisc R offers additional retention times for analytes which are not given with a conventional reversed-phase column.

Sielc Obelisc N HPLC Column
The Obelisc N HPLC column is particularly suitable for the separation of polar and charged analytes due to its polar properties. Through positively and negatively charged functional groups, it is possible to interact with diverse charged analytes and separate them from each other by different retention times.
All Obelisc N HPLC columns from SIELC are available in different versions:

The Coresep HPLC columns are now produced by HelixChromatography. They all are reversed phase columns with embedded basic or acidic functional groups, thereby improving the retention of ionic compounds. All mobile phases are compatible with LC-MS and preparative chromatography in a pH range between 1.5 and 5.
All CORSEP HPLC columns now from Helix Chromatography are available in different versions:
Inner diameter [mm] |
4.6, 3.2, 2.1, 1, 0.5, 0.25 |

Choose between different stationary phases: Coresep 100, Coresep S or Coresep SB to obtain the best possible separation result.
SHARC ™ HPLC columns are the latest innovation from SIELC Technologies and represent the first columns in which the separation is mainly based on hydrogen bonds. SHARC stands for Specific Hydrogen-bond Adsorption Resolution Chromatography (Specific hydrogen bonds adsorption dissolution chromatography). Hydrogen bonds are the interaction between a positively polarized hydrogen atom bound to an electronegative atom such as oxygen, nitrogen, and fluorine with a second electronegative atom.
