Summary:

In this study, we developed an optofluidic device for analyzing the mass transfer of materials in a microfluidic channel. This device uses refractometry to monitor concentration in contrast to typical methods which use florescent markers. This is ideal for situations where a sample is unable to be florescently labeled. This study focuses on the mass transfer of high concentrations of calcium chloride. Specifically, we analyzed the effect of density and viscosity on the mass transfer.
