After a grinding of ~ 50 g of sample, ground particles inside of the collecting vessel reacted with oxygen from air and started to burn!
For this, the complete machine should be placed inside of a glove-box which will be flushed with nitrogen.
It is also possible grinding a higher amount of sample with a Planetary Mill PULVERISETTE 5 classic line and grinding bowls with gassing lids to flush the bowls with inert gasses (like nitrogen or argon etc.)
