Pyrolyses silver capsul fall over crucible

Hello Everyone,

I`m working only since July 2020 with EA-IRMS (Thermo EA Isolink Delta V Advantage). In the last weeks we meassured a lot with the pyrolysis reactor, after every ~150 samples I cleaned the crucible. Today I remove the complete reactor and change the silver wool and the glassy carbon granulate and there I see, that a lot from the silver capsules is backed with the granulate.

Is it normal that not every sample fell in the crucible? Or do you have any idea how i can prevent this?

Thank you for your attention and stay healthy.

Best regards
