          Rt-ßDEXm

          (permethylated ß cyclodextrin doped into 14% cyanopropylphenyl/86% dimethyl polysiloxane e)

          GC columnBy adding ß or y cyclodextrin to our bonded Rtx®-1701 stationary phase, we greatly enhance overall utility and column lifetime for the chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. Refer to the applications section of this catalog for examples, or call our Technical Service chemists for assistance in matching a column to your chiral analysis.

          Applications
          • General purpose chiral phase with many published applications.
          • Terpenes
          • Alcohols

          Rt-PAH

          (proprietary liquid crystalline phase)GC column

          • Specially designed for the analysis of polycyclic aromatic hydrocarbons (PAHs) listed in US EPA methods 610 and 8100.
          • Compatible with MSD.

          The stationary phase of this column is specially designed for separation of isomeric polynuclear aromatic hydrocarbons. Specifically, it provides fast analysis of EPA Method 610 PAH mixture. The stationary phase is cross-linked and chemically bonded, which dramatically lowers the bleed at elevated temperatures, making the column compatible with MS detector.
