Once in place, ii) the inner lead -- no longer needed for mechanical stability -- then could be retracted. | |
| Jun 22 at 11:39 | comment | added | Buttonwood | @Maurice This part of the question possibly was addressed: a sitting drop electrode (though not with Hg...) gliding over a sample, coupled with the resolution of an AFM (example). Perhaps such tips (with capillaries mounted) are commercially available, too? | |

decipher the abbrevation "SECCM" and addition of two references to make the question more meaningful to a more general audience of chemistry.se

| Jun 21 at 21:13 | comment | added | DrMoishe Pippik | It would help if you were more specific about the hole and capillary size (10 µm? 1 µm?), and the material of the substrate. If the metal can withstand it, clean with an ultrasonic bath to dislodge the glass, or use warm, strong NaOH solution in an ultrasonic bath (under a hood, while wearing face protection and gloves!) to dissolve the glass. | |
| Jun 21 at 20:28 | comment | added | Maurice | Please explain ! What is the meaning of SECCM ? What and where are the electrodes ? What is the composition of the electrolytes ? Why do yo need nitrogen ? | |
