Thermodynamic properties of novel phenylene-bridged periodic mesoporous organosilica as high performance liquid chromatographic stationary phase
|
Abstract:
The thermodynamic properties of spherical phenylene-bridged periodic mesoporous organosilica (PMOs) as high performance liquid chromatographic stationary phase were investigated and compared with commercial grafted C18 and phenyl stationary phases.The retention behavior of several compounds of polycyclic aromatic hydrocarbons (PAHs) was investigated.The thermodynamic parameters of transfer from mobile phase to stationary phase were discussed.The results showed that the enthalpy-entropy compensation effect d...
