90% biscyanopropyl/10% phenylcyanopropyl polysiloxane
- General purpose columns for cis/trans FAMEs, dioxin isomers.
- Temperature range: 0°C to 275°C. (Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced maximum temperature.)
- Equivalent to USP G48 phase.
Rtx®-2330 features cyano groups on both sides of the polymer backbone that give the phase a strong dipole moment and high selectivity for cis/trans compounds or compounds with conjugated double bonds. Highly polar columns typically exhibit poor column efficiencies, high bleed, and short column lifetimes when thermally cycled. To overcome some of these problems, Rtx®-2330 utilizes a surface treatment more compatible with the Rtx®-2330 phase. In addition, an improved polymer produces columns with improved column efficiency and lower bleed.
Because the Rtx®-2330 stationary phase is not 100% bonded, it should not be solvent rinsed.
