AB  - Butyl-methacrylate-based porous monoliths were rapidly prepared in the 
      fused-silica capillary with a 10-cm stripe of polyimide removed from its 
      exterior. The photopolymerization could be carried out in 150 s using ethylene 
      glycol dimethacrylate as a cross-linking agent; 1-propanol, 1,4-butanediol, and 
      water as tri-porogenic solvents; and Irgacure 1800 as a photo-initiator. The 
      effect of different morphologies on the efficiency and retention properties was 
      investigated using pressure-assisted CEC (p-CEC), CEC, and low pressure-assisted 
      liquid chromatography modes (LPLC). Baseline separation of the model analytes was 
      respectively achieved including thiourea, toluene, naphthalene, and biphenyl with 
      the lowest theoretical height up to 8.0 microm for thiourea in the mode of p-CEC. 
      Furthermore, the influence of the tri-porogenic solvents on the morphology of 
      methacrylate-based monoliths was systematically studied with mercury intrusion 
      porosimetry and scanning electron microscopy.
