TY - JOUR TI - Time resolved electrophoretic and electroosmotic velocities DO - https://doi.org/doi:10.7282/T30P0X3H PY - 2013 AB - Electroosmotic pumps show promise in many fields. For example, several lab-on-chip devices have been proposed the make use of these devices (1). This thesis will focus on finding the fluid velocity distribution inside an electroosmotic pump. First, the fluid velocity was calculated for an electroosmotic pump using a bipolar pulse train voltage. Next, the particle velocity for particles suspended in the fluid was found. A glass electroosmotic pump was constructed using a glass capillary tube. Using a 1mM Borate buffer solution and 0.5µm Fluosphere particles, time resolved micro particle image velocimetry (TRµPIV) was performed on the pump to obtain the particle velocity distribution inside the pump. The experiment fluid velocity was calculated from this particle velocity. The experimental particle and fluid velocities show excellent agreement with the theoretical calculations.
