Capillary Electrophoresis (Part 4): Electropherogram & Migration Time

This video is Part 4 of 6 for the e-Lectures series of NUS Chemistry CM3292 experiment titled "Capillary Electrophoresis (CE) of Inorganic Anions".
Contents:
0:49 Migration time
2:31 Factors affecting the migration time
5:32 Absorbance & Corrected peak area
By the end of this e-lecture, students will be able to:
1. Compute the migration rate of individual analyte from its migration time and length to the detector.
2. Discuss the factors affecting the migration time.
Thanks for watching :)

Best video on capillary electrophoresis....keep uploading
Thank you..

[@FrancisChongYY]

@Vaibhav Deshwal, thank you so much for your kind words :) I will be working on more videos soon :)

[@Arshzal]

ur video helped me in preparing exam..thankyouuuu/..u deserve the bestttttttt

[@sivasable]

That's a wonderful explanation!!! Very easily understood!!!
If you don't mind could you please explain the difference between CZE and CGE in a simple way?
Thanks🙂

[@user-ym6ps9df5x]

great explained

[@amiramnd8964]

very well explained, thank u so much

[@FrancisChongYY]

You're very welcome! @amira mnd. Thanks for watching :)

Nice video's! Could you explain what the dip 'peak' is around the 2 minutes?

[@FrancisChongYY]

Dear Sharon Sap, thank you. In this case, the "V" in a circle at around 2 minutes represents the voltage applied. If you are referring to the "dip" observed in an electropherogram, please check out my other video (Part 4.2) in which we discuss the "Indirect Absorbance Detection" at around 3:33.

ok thank you.. but if someone ask me to quantitative analysis of ibuprofen using CE i.e how much of that is present in my sample_ How wud CE help me to find this?
