AB  - In this work, open-tubular capillary column coated with zeolite imidazolate 
      framework-8 (ZIF-8) nanocrystals was prepared by a layer-by-layer method. The 
      coating was formed by growing ZIF-8 nanocrystals on either bare fused silica 
      capillary wall or the capillary column premodified with amino groups. The shape 
      and the thickness of the coating formed by using these two methods were almost 
      the same. However, the coverage of the ZIF-8 crystals on the bare fused silica 
      capillary wall was higher than that on the capillary column premodified with 
      amino groups. The ZIF-8 coated capillary column was evaluated for open-tubular 
      capillary electrochromatography. The effect of pH value, buffer concentration, 
      and applied voltage on the separation of phenols was investigated. Good 
      separation of nine phenolic isomers was achieved because of the strong 
      interaction between unsaturated Zn sites and phenols. The column performance for 
      o-nitrophenol was as high as 208 860 plates m(-1) . The run-to-run, day-to-day, 
      and column-to-column reproducibility of retention time and resolution for 
      p-nitrophenol and o-nitrophenol were very good with RSDs of less than 6.5%.
