        Rtx-50

        (Crossbond® 100%methylphenyl polysiloxane)GC column

        • Midpolarity phase.
        • Equivalent to USP G3 phase.

        The high thermal stability of Rtx®-50 columns makes possible dual-column analysis with common phases such as Rtx®-1ms or Rtx®-5ms. Between analyses, high temperatures can be used to drive less volatile contaminants off of the column.
