: Restek
Rtx-DHA (fused silica) columns are crossbond with 100% dimethyl polysiloxane, which is optimised for hydrocarbon analysis.
- Peak symmetry for polar oxygenates
- Stable to 340 °C
- Similar phases: HP-PONA, DB-Petro, CP-Sil PONA C8, Petrocol DH, BP1PONA
: Columns 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.The ASTM D6730 method also requires a tuning column—Rtx-5 DHA tuning column.
