查询词典 ratios

Separation of racemic mixtures of thirty-eight secondary aromatic alcohols and arylethanediols with different substituting group was achieved with HPLC by using Chiralcel OD and Chiralcel LJ as chiral stationary phase and hexane/2-propanol mixtures of different ratios as eluents. The chromatographic parameters of these racemates on OD and OJ columns were examined.
