Platisil™ PH (New)

-->

Platisil PH columns are well-suited for the separation of aromatic and polar compounds in RP mode. The retention characteristics are similar to those of the C8 phase, but with lower hydrophobicity. The presence of the phenyl functional group provides π-π interactions and offers alternative selectivity compared to traditional alkyl bonded phases, thereby expanding the range of selectivity options available. These columns provide sharp peaks and great reproducibility run-to-run, column-to-column, and batch-to-batch. The high coverage combined with a thorough endcapping makes Platisil PH columns more stable and durable.

 

Features of Platisil™ PH Columns

•  Monomerically bonded phenyl group
•  Alternative selectivity from π-π interactions
•  Exceptionally high surface coverage and superior stability
•  Lower hydrophobicity than C8 columns for rapid elution of hydrophobic analytes
•  Excellent resolution and reproducibility
•  Suitable for the separation of polar compounds, aromatic compounds, and isomers
