Cogent HPLC columns have a silicon hydride surface similar to other TYPE-C™ phases but the uniqueness of Phenyl Hydride™ is that they have unique selectivity for compounds with aromatic rings with all the TYPE-C silica benefits.

• Excellent for Aromatic Compounds 
• Use in RP or ANP
• TYPE-C™ Silica

Direct silicon carbon bonds and the silica hydride surface give these columns extremely long life times compared to other phenyl columns based on ordinary silica.

Used also with LCMS because there is no endcapping that will bleed into your MS as with most other phenyl columns.
