Capillary Electrophoresis (Part 3): Electrophoretic mobility

This video is Part 3 of 6 for the e-Lectures series of NUS Chemistry CM3292 experiment titled "Capillary Electrophoresis (CE) of Inorganic Anions".
Contents:
0:34 Electrophoretic mobility
1:04 Factors affecting Electrophoretic mobility
3:57 Combining Electrophoretic mobility and Electroosmotic flow (EOF)
By the end of this e-lecture, students will be able to:
1. Describe the basic principles of electrophoretic mobility
2. Predict the migration order of cations, anions, and neutral species in CE based on understandings of electrophoretic mobility and EOF
Thanks for watching :)

    Sir, your videos are really helpful for me , in this video In last you explained all anions and cations moves towards cathode can you explain again why ?

  • @FrancisChongYY

    @FrancisChongYY

    4 жыл бұрын

    Hi @Vikas Singh, thanks for watching. Yes, the anions and cations move towards the cathode in this particular example because in general, the electroosmotic flow (EOF) is usually greater than the electrophoretic mobility of both anions and cations. You may refer to 4:07 of the video for more information. And also, please kindly take note that in the case of reversed EOF, the anions and cations move towards the anode instead. You may refer to my other video on reversed EOF for more information: kzread.info/dash/bejne/ooRozbylery6qdI.html Thank you :)

    Hi @Er Amit Jangra, thank you. You may check out some journal articles that discuss/review the principles and applications of CE. As for textbook, Principles of Instrumental Analysis (Cengage Learning) may be a good place to start. For more advanced reading, you may check out my colleague's book: books.google.com.sg/books?id=M2Ys3VSG0nAC&lpg=PR6&dq=capillary%20electrophoresis%20sam%20li&pg=PP1#v=onepage&q=capillary%20electrophoresis%20sam%20li&f=false
