YMC-Pack Phenyl Capillary Guard Columns

Unique Selectivity

Phenyl columns provide unique selectivity when compared to aliphatic straight chain reversed-phase materials such as C18, C8, and C4.  The π electrons of the phenyl group can interact with the aromatic ring(s) of an analyte to increase retention relative to non-aromatic species.  Phenyl also has application as an alternative to C18 and C4 for the analysis of peptides and proteins on both small-pore (120Å) and wide-pore (300Å) silica supports.  Retention is decreased on wide-pore phenyl phases relative to 120Å material.  Generally, as pore size increases, surface area decreases, resulting in shorter retention times.

Specifications

Capillary Guard Columns: Features & Benefitsymca_3

Guard columns are recommended for challenging matrices or for use as trapping columns.  YMC capillary guard columns are connected directly to the analytical column using the supplied column coupler.

A column coupler is supplied with every pack of YMC capillary guard cartridges to guarantee an optimum connection with low dead volume.  A polymer-based (PCTFE) coupler is provided for 1/16” columns, while a stainless steel coupler is provided for 1/32” columns.  Additional couplers can be purchased separately if required.
