Restek, 13397, Rxi-1ms GC Capillary Column, 12 m, 0.20 mm ID, 0.33 µm

The Rxi-1ms capillary GC column is a low-bleed, nonpolar stationary-phase column for gas chromatographic analysis of volatile and semivolatile organic compounds. Its dimensions are 12 m length, 0.20 mm internal diameter and 0.33 µm film thickness. This compact format can support rapid screening of suitable mixtures while maintaining chromatographic separation through careful control of the oven program and carrier-gas conditions. The Rxi-1ms phase is useful for hydrocarbons, solvent impurities, gasoline-range organics, essential oils and other samples requiring a general-purpose low-polarity separation. Low stationary-phase bleed helps protect baseline quality, particularly with mass-spectrometric detection. The operating temperature range is −60 to 330/350 °C, subject to the applicable programmed and isothermal limits. A suitable injector, ferrule and detector connection are required for the 0.20 mm bore. Choose film thickness and sample loading to avoid column overload. The item is one finished fused-silica GC capillary column, not loose packing or a six-column bundle.
