I'm not familiar with the Kiel setup, but we experienced problems with forams jumping out of the 'buckets' on the carousel of the VG Isocarb (though ostracod shells didn't). I presume this resulted from slight jiggling of the buckets as the carousel turns round. Yes, the solution was to crush them.

Subject: [ISOGEOCHEM] jumping ostracod shell in Kiel device

Dear subscribers

I am running single ostracod shells on a MAT252 with a Kiel device, and we found that some of the
valves were not completely dissolved. We realised that in such situation the shell, or part of it,
was on the top of the vial, so that it may have jumped probably due to a bubble during the reaction
with acid.

Has anyone of you found this problem before? Could you give any recommendation? 
One possible way to avoid such a jump would be crashing the shell. Some ideas on this or any other

Thanks in advance
Best wishes
