Identification of Corrected Retention Indices of Ten Phenols in Reversed-Phase High Performance Liquid Chromatography
反相高效液相色谱法测定酚类化合物的保留指数

Corrected retention indices in RP-HPLC of ten phenols based on 2-keto-alkanes were examined on three ODS-silica columns. The RI values for phenols showed large variations. However , when the correction was applied, the variations diminished significantly. It is clear that the correction procedure improves the variation of phenols' RI values obtained from different ODS columns. The procedure is recommended as a method of standardization of HPLC data.
