AB  - Because of the unusual properties of the structure, the metal organic frameworks 
      (MOFs) have received great interest in separation science. However, the most 
      existing methods for the applications of MOFs in separation science require an 
      off-line procedure to prepare the materials. Here, we report an in situ, 
      layer-by-layer self-assembly approach to fabricate MIL-100(Fe) coated open 
      tubular (OT) capillary columns for capillary electrochromatography. By a 
      controllable manner, the OT capillary columns with a tailored MIL-100(Fe) coating 
      have been successfully synthesized. The results of SEM, XRD, FT-IR, and ICP-AES 
      indicated that MIL-100(Fe) was successfully grafted on the inner wall of the 
      capillary. Some neutral, acidic and basic analytes were used to evaluate the 
      performance of the MIL-100(Fe) coating OT capillary column. Because of the size 
      selectivity of lattice aperture and hydrophobicity of the organic ligands, three 
      types of analytes were well separated with this novel MIL-100(Fe) coating OT 
      capillary column. For three consecutive runs, the intraday relative standard 
      deviations (RSDs) of migration time and peak areas were 0.4-4.6% and 1.2-6.6%, 
      respectively. The interday RSDs of migration time and peak areas were 0.6-8.0% 
      and 2.2-9.5%, respectively. The column-to-column reproducibility of retention 
      time was in range of 0.6-9.2%. Additionally, the 10 cycles OT capillary column 
      (10-LC) could be used for more than 150 runs with no observable changes on the 
      separation efficiency.
