[labnetwork] Sharpie for charged particle beams

[Michael Yakimov]

Since nobody else chimes in, my 2 cents:

I was told black sharpie industrial is the one to use. Works great for me - granted, my samples are not very insulating.
Probably makes sense to say "black" as that is likely to be carbon-filled hence conductive. Looks like high-temperature feature of "industrial" means carbon.
I also tried Sakura Micron archive pen - for sharper tip. It worked, although I don't have very favorable memories of that. IIRC  film was too thick inhibiting navigation.

Hi everyone,

I am wondering if you ever worked with a Sharpie marker that is conductive and has the right viscosity to deliver a reasonable thickness as a protective layer for generating cross-sections for example using a focussed ion beam.

I have heard mixed reviews on ink pigments, some recommend using specific colours and others recommend avoiding some colours. Can you please share any experiences you had working with Sharpie markers/colours/tip thickness/other marker brands for this purpose?



Thanks,
