Capillary Electrophoresis (Part 2): Instrumentation & Electroosmotic Flow
Channel: Francis Chong
Date: 25/02/2019

This video is Part 2 of 6 for the e-Lectures series of NUS Chemistry CM3292 experiment titled "Capillary Electrophoresis (CE) of Inorganic Anions". 

Contents:
0:18 Instrumentation of CE
3:01 Electroosmotic flow (EOF)
6:29 Unique flat flow profile of EOF

By the end of this e-lecture, students will be able to:
1. Describe the basic instrumental setup of CE.
2. Explain the origin of EOF in terms of the Surface Chemistry of the fused silica capillary, the fixed layer, and the diffuse layer.
3. Predict the direction of the EOF when an electric field is applied.
4. Compare and contrast the Flat flow profile of EOF in CE and the Parabolic flow profile of Pressure-induced flow in HPLC.

Thanks for watching :)
