Rtx-DHA Columns (fused silica)

Crossbond 100% dimethyl polysiloxane—optimized for hydrocarbon analysis
  • Columns meet or exceed all ASTM D6730-01 and CAN/CGSB 3.0 No. 14.3-99 method guidelines; test report for method D6730 supplied with each column.
  • Excellent responses and peak symmetry for polar oxygenates.
  • Stable to 340 °C.

Don't forget: The ASTM D6730 method also requires a tuning column—Rtx-5 DHA Tuning Column

Gasolines are complex mixtures of hundreds of compounds. Information about concentrations of the individual components is important for evaluating raw materials and for controlling refinery processes. ASTM D6730-01 outlines a high-resolution GC method for detailed hydrocarbon analysis (DHA) of gasolines. Rtx-DHA columns are ideal for DHA methods and easily meet or exceed both ASTM D6730-01 and Canadian General Standards Board CAN/CGSB 3.0 No. 14.3-99 requirements. Every Rtx-DHA column is tested for retention, efficiency, stationary phase selectivity, and bleed—guaranteeing reproducible column-to-column performance.
