Similar Phase(,s),: VF-23ms

Rtx®-2330 is one of the most polar capillary column stationary phases. Cyano groups on both sides of the polymer backbone 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, we developed a surface treatment that is more compatible with the Rtx®-2330 phase. In addition, our improved polymer produces columns with better column efficiency and lower bleed.

Because the Rtx®-2330 stationary phase is not 100%, bonded, it should not be solvent rinsed.
