窄分布聚苯乙烯在NDG(硅烷化刚性硅胶)柱上,以苯、甲苯、THF和MEK作为淋洗剂时,流体力学体积?[η]和校正的流体力学体积?[η]/f(θ)能否作为普适校正参数,关键在淋洗剂的极性。若淋洗剂的极性为零或很小,则成立。由于淋洗剂极性分子受填料表面残存静电作用力的吸引,它的表面上形成一个受束缚的淋洗剂液层,减小了孔道的有效尺寸,使logM[η]-Ve线和logM[η]/f(θ)-Ve线向Ve减小方向移动。
Narrow distribution of polystyrene on NDG (silanized rigid silica) column with benzene, toluene, THF and MEK as eluent, the hydrodynamic volume [η] and corrected hydrodynamic volume [η] / f ( θ) can be used as universal calibration parameters, the key in the eluent polarity. If the polarity of the eluent is zero or very small, then established. As the polar molecule of the eluent is attracted by the residual electrostatic force on the surface of the filler, a leached eluent layer is formed on the surface of the eluent and the effective size of the pore is reduced so that the logM [η] -Ve line and the logM The [η] / f (θ) -Ve line moves in the Ve decreasing direction.
