    Capillary action is created by the tendency of polar molecules ( such as water) to adhere to other polar things (the walls of a thin tube). As a result you can't just use any solution as you stated or at least you'd want to match the polarity of the solvent to the tubing. In this case I don't think it really matters because capillary action doesn't seem to drive the migration, the electric charge does. The only consequence of using a small diameter tube is to increase the relative surface area that your analyte see and there by increase the resolution of the instrument (you don't have to run it through as much tubing). It's also nice because small tubes use less solvent and save money.

    very good video but unfortunately i got frustrated by the ringing of the phone.

    Good video. Can you explain stacking? When using electrokenetic injection, having the ionic strength in the sample buffet lower than the column buffer. Is he electric field higher in the sample?

    Great, video thanks! Question, wouldn't smaller molecules have a larger diffusion coefficient? If not, why not?

    Using headphones helps with the audio although only the left side works.
    And as for people complaining about his face being there, it honestly helps! Lol.
    Plus, some other youtube lecturers do it as well.
    LOVE YOU SHOMU.
    I'm your biggest fan.

    Whether Buffer and sample are different? What kind of buffer is used in CE for sample separation .

    Good evening sir I could follow your brilliant presentation on capillary electrophoresis; However I'm having trouble with neutral molecules such as Nifedipine I can not ionize and I seek your expertise as I work on quality control of this molecule in Senegal by capillary electrophoresis method. My name is Ariel

      so you work in the field but have no clue what to do? How is it your job yet you have to ask some random person on the internet how to do it

    Can you help me to understand what the detection potential is?
    I already know the CE voltage, but in my methodology said that the detection potential is 1.20 V, and I don't know what that's means
    Thank you

    Bhaiya that means the molecule coated on capillary will be fixed and negative. But the analyte will have charge depending on ph know

  • @muskangoel3567
    @muskangoel3567 4 года назад

    My question in... When +ve molecules move towards negative and -ve silica ions present on inner surface of capillary then movement of +ve is not hindered by negative charge as +ve attract to negative of silica ion.

      By aplying pressures through pump or some thing the positive species force to move out from capillay and attracted towards other side that is cathode

    Wrong bro! Cof ????? You say chemiosmotic force.... That is totally wrong... Please check it... And you say eof (electroosmotic force) not force but flow... Please correct it for new students..

    It is a common sense if u r making a video u should keep ur phone silent as ur 1st priority should be the explanation nobody wants to knw which phone u use lol!
