New COSMOSIL PFP and PBr HPLC Columns
Mar 01 2014
Nacalai Tesque have launched COSMOSIL 5PFP, a pentafluorophenyl-bonded HPLC column with alternative selectivity to C18 columns. In addition to a hydrophobic separation mechanism, the phase offers dipole-dipole and p-p interactions. COSMOSIL 5PFP shows good retention for compounds with strong dipole moments, such as cationic or halogenated compounds, and exhibits high steric selectivity for structural isomer separations. Columns with analytical to preparative dimensions are available.
The new COSMOSIL PBr column is a pentabromobenzyl bonded phase designed for the reversed-phase separation of polar compounds that may not require HILIC separation conditions. Separations are achieved using a combination of hydrophobic and dispersion forces.
For further information on these or any other COSMOSIL column, please contact Hichrom Ltd.
