Abstract

In this study, the electrical conductivity of low-volume samples was measured using a prototype microfluidic chip with electrodes. We were able to show the difference of electrical conductivity in the samples of saline solution (0.9w/v% NaCl solution) with sucrose. The correlation between the electrical conductivity and the viscosity evaluated by the capillary method was shown. This correlation was shown that it is possible to evaluate viscosity based on the Walden's rule with our chip.

用微流控芯片测量电导率并用Walden规则评价粘度

在这项研究中，使用带有电极的原型微流体芯片测量了低体积样品的电导率。我们能够显示含蔗糖的盐水溶液（0.9w/v%NaCl溶液）样品的电导率差异。显示了通过毛细管法评估的电导率和粘度之间的相关性。这种相关性表明，可以使用我们的芯片基于Walden规则来评估粘度。
