Brilliant video, it's kinda hard to visualise the Taylor cone on a standard ESI source. Thanks!

can i ask if why the usage of a sharp needle is employed here? why not use a blunt needle?

Hi there, The original syringe needle tip has been removed. It is blunt. You can see it in the beginning of the video when the solution is forming a droplet and the field is off. The tip that appears while the applied field is the Taylor cone formed on the liquid itself. Cyro

Hi Sherif, Unfortunately I do not have any. Cyro

Hi there,

Yes the field is between the needle and a grounded sample holder. Its shape it’s very complex due to the sharpness of the needle. The ejected solution, which is charged, makes it even more complicated. We do not worry with the field shape. We just connect the high voltage source to the needle and the sample holder (collector) to the ground. (Use low current sources for safety)

does the field is between this needle itself and the surround of its end, isnt it?

excellent video, extremely instructive!
