Rtx®-1701
Rtx®-1701 Columns (fused silica)
(midpolarity Crossbond® phase)
• General-purpose columns for alcohols, oxygenates, PCB congeners
(e.g., Aroclor mixes), pesticides, and fragrance compounds.
• Temperature range: -20 °C to 280 °C.
• Equivalent to USP G46 phase.
Rtx®-1701 is one of the more popular stationary phases used in capillary GC. The mix of
cyano and phenyl functional groups increases the polarity and offers a different elution
order relative to less polar Rtx®-1 or Rtx®-5 columns. An Rtx®-1701 column is ideal for
confirmation analysis in combination with an Rtx®-35 or Rtx®-5 column. The polymer is
fully characterized to ensure long-term reproducibility, column-to-column consistency,
and low bleed, even with sensitive detectors such as ECDs and MSDs. similar phases
