        Rtx-35 MS

        (Crossbond® 35% diphenyl/65% dimethyl polysiloxane)GC column

        • Midpolarity phase.
        • Column specifically tested for low bleed performance.
        • Equivalent to USP G42 phase.
        • Rtx®-35 columns are available with Integra-Guard™ built-in guard column.

        An Rtx®-35 column is a popular confirmation column for pesticides and herbicides, in conjunction with an Rtx®-5 or Rtx®-1701 column. The higher phenyl content causes useful elution order and retention time changes.
