Summary The capacity factors and retention indices, based on the alkylarylketone scale, of ten barbiturates and a set of five column
test compounds have been compared on a series of different octadecylsilyl bonded (ODS) silica columns under identical elution
conditions of 40:60 methanol-buffer pH 8.5 at 30 °C. The retentions were highly reproducible on columns prepared from the
same batch or different batches of ODS-Hypersil, but large differences in the capacity factors were found when column packings
from different manufacturers were compared. Retention indices were more reproducible than capacity factors but they could
not compensate for differences between the different packing materials.

Bonded phase ODS-silica has been prepared using purified silica prepared from rice husk by burning, reflux with sodium hydroxide
solution and precipitation as a gel. The gel was spray dried, further purified by washing with concentrated hydrochloric acid
then distilled water prior to vacuum drying and silanization and end-capping. The product’s physical and chromatographic properties
are reported. 相似文献
