7 Special points in connection with automatic sample changers 

Increasingly, automatic sample changers are being used. This poses particular problems since the samples on the turntable waiting for measurement must be protected against loss of volatile components such as moisture, and against the uptake of water or oxygen from 

The sample is protected against direct contact with the surrounding atmosphere by placing an aluminium lid on top of the crucible. The Kd is then removed and held by the sample robofs gripper during the measurement. In this case, alumina or other high-temperature crucibles can be used. 

An aluminium crucible is sealed with a perforable aluminium lid and then automatically pierced, or opened, immediately before insertion into the measuring cell. In this case, the maximum temperature of the experiment is limited to 640°C to prevent melting of the crucible.
