YMC-Triart PFP

YMC-Triart PFP is a pentafluorophenyl bonded phase. The selectivity is unique owing to the various forces arising from hydrophobic, π–π, and dipole–dipole interactions.
YMC-Triart PFP is especially effective for improving the separation of aromatic compounds, nitro compounds, and halogen compounds because the selectivity is very different from that of other columns.

Features

Unique separation provided by various interactions

As the differences in the hydrophobicities of the cis-trans isomers of piperine, which is a pungent component of pepper, are small, commonly used reversed phase columns are not suitable for their separation. However, YMC-Triart PFP provides excellent separations as it recognizes minor charge localizations in a molecule owing to various binding through as π–π and dipole–dipole interactions. YMC-Triart PFP shows high selectivity towards compounds with small structural differences.
