WebJan 15, 2010 · In liquid chromatography, the viscosity of the mobile phase plays crucial role. It influences the maximum pressure used. Clearly, the mobile phase with lower viscosity shows lower instrumental pressure. Thus, higher flow rates of the mobile phase can be used and lead to the shorter analysis time. Following tables and plots show dependence of ... http://www.chromatographer.com/mobile-phase-viscosity/
