Rxi-65TG Columns (fused silica)

High-polarity Crossbond phase
  • Ideal for the analysis of triglycerides in edible oils.
  • Excellent thermal stability up to 370 ˚C ensures consistent results and longer column lifetimes.
  • Separate and quantify critical triglycerides (acylglycerols) without interference from column bleed.
  • Observe even underivatized mono- and diglycerides.
  • Novel manufacturing techniques ensure consistent column-to-column quality.

Note: the Rxi-65TG column is recommended for analyzing mono-, di-, or triglycerides in edible oils. If you are analyzing triglycerides in biodiesel fuels, use either our Rtx-Biodiesel TG or MXT-Biodiesel TG column.

What do Rxi columns mean to you? Three things:

  • Ultra-low bleed.
  • Exceptional inertness.
  • Reproducible performance, column after column.

Rxi fused silica capillary GC columns were designed specifically to be the best columns available for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi columns will have long lifetimes. Restek chemists have also developed a stable, reproducible manufacturing process so that Rxi columns will meet your needs every time you install a new column.

Marking a significant advancement in high phenyl content GC stationary phases, the Rxi-65TG column combines both chemistry and manufacturing innovations to produce an exceptionally low bleed column for the analysis of triglycerides in edible oils. With a selectivity similar to our Rtx-65TG column and much greater thermal stability, an Rxi-65TG column is a direct replacement for any methods using the older Rtx version.
