Supercritical Fluid Chromatography (SFC) - PBr (Pentabromobenzyl)

Nacalai Tesque COSMOSIL 5PBr Pentabromobenzyl Semi-preparative SFC Column, 5µm, 120Å, 20mm I.D. x 250mm Length, 1/Pk

Product Number: 13853-11

Unique separations using dispersion force

Supercritical Fluid Chromatography (SFC) has become more attractive because it offers some advantages over HPLC, such as high speed, unique selectivity and environmentally friendly separations. Many conventional normal-phase stationary phases, such as diol, amino and cyano, have been used for SFC applications. However, these phases present limitations for separations. COSMOSIL SFC Columns have been developed to enhance the capability of SFC separations.

Nacalai Tesque has developed columns specially designed for SFC in collaboration with Nacalai USA and Pfizer, Inc. Global R&D: COSMOSIL HP, PY (equivalent to 2-ethylpyridine) and Quinoline. In addition to these, our HPLC columns Cholester and PBr have been tested for use with SFC.

Cosmosil® PBr Columns

  • Separate hydrophilic compounds in reversed-phase conditions
  • Simple mobile phase condition compared to HILIC
  • More sample loading capacity than HILIC
  • Alternative selectivity to C18 column

Dispersion force:

London dispersion force is a weak intermolecular force that results from dipoles temporarily induced from random unsymmetrical electron positions in two adjacent atoms, also known as "instantaneous dipole-induced dipole force". It is present in all molecules, regardless of whether they are polar or non-polar. Compounds with high polarizability have stronger dispersion force.
