Thanks all for the suggestions!
What sort of glue/epoxy do you use to attach the coverslip to the underside, and does it make any difference to the appearance of the sample in an optical microscope?
Cheers,

Hi Riia,
I have had success with something similar to Vincent’s suggestion but using a thin cover glass on the underside of the section and gluing or epoxying the broken pieces onto it. It is still a bit fragile but more robust than just gluing pieces together. It has the advantage over using another glass side underneath in that the thickness is barely increased - this is critical to us who are using Camera probes (and shuttles) where there is a rather severe limit on the z-axis motion.

Hi Riia,
If you have the space in the sample holder, glue a slide to the bottom with resin. That provides support and I have found that most survive afterwards. Super glue can degas in the microprobe, so I always use resin (e.g. epothin, petropoxy, etc). If you choose your resin carefully, this extra slide will not even really affect your optical properties. Hope this helps.
Best,
Vincent

Greetings,
Can any of you recommend a good way to fix a broken thin section? I have one which broke, so I glued it back together with some locally available "super glue", and it held for some weeks. It was ok with being in the spring-loaded sample holder for our LA-ICP-MS for a number of sessions, and even survived being attached to the clamp and copper-tape attachment to the sample holder for the SEM, until we tried to take it off of that sample holder, when it separated upon the previous breaks. I tried re-gluing it, but on the second attempt the three pieces just came apart again when I set it into the spring loaded LA-ICP-MS sample holder. We would like to do further analysis of this sample in the laser lab, but I really don't want it coming apart in the holder, which could cause it to jam inside the machine, if the spring were to push one of the pieces up above the plane of the holder. Thank you for suggestions you may have.
Thanks,
--Riia
