Benzodiazepines
TheRtx®-200 stationaryphaseprovides excellent
resolution and peak shape for benzodiazepines.
The unique selectivity of the Rtx®-200 trifluoro-
propylmethylpolymerhelps toresolve thisgroup
of compounds, which are very closely related
structurally.Thehigh thermal stabilityof the sta-
tionary phase provides a stable baseline at high
temperature, to facilitate analysis of picogram
quantities of thesematerials.
