Application of Diol column under adsorption and mixed partition-adsorption normal-phase liquid chromatography mode for the separation of purines and pyrimidines
چکیده انگلیسی
The diol-bonded phase (column LiChrospher 100 Diol) has been studied for the separation of some purines and pyrimidines under normal-phase liquid chromatography (NPLC) conditions. Retention time, column efficiency, and selectivity of column with diol-phase were compared to those of unmodified silica (column LiChrospher SI-60). It was established that under adsorption NPLC mode application of diol-phase can reduce the separation time and a little improve the column efficiency. Significant improvement of the column efficiency for polar solutes is observed if mixed partition-adsorption NPLC mode is used. The investigation has shown that application of diol-phase instead of bare silica is useful not only under adsorption, but also under mixed partition-adsorption mode if the system with specific selectivity is necessary.
