| + * the choice of an adequate container: |
| + ** does the sample react with the container? For metallic |
| + samples, please check the phase diagrams of possible allows |
| + which might be created when the sample reacts with the container |
| + or sample stick. |
| + ** is the sample outgasing? It is preferred to work with |
| + either an open container, or with a container connected |
| + to a tube sample stick, allowing to control the atmosphere |
| + from outside. |
| + * the thermocouples have to be fixed well, and the proper |
| + calibration curve has to be selected. |
