The degradation byproducts from the sample leave the instrument directly via a small hole in
the furnace cover. These byproducts could be harmful so use adequate protection such as
placing the instrument in a fume hood. There is some condensation of less volatile products
on the cold spots of the analyzer: the lower side of the cover and the upper inner side of the
cooling jacket. These spots can be cleaned easily with a suitable solvent. Condensation may
also occur on the top inner side of the cooling jacket. To prevent this, use the porous
ceramic furnace cover to absorb the less volatile byproducts. When necessary, this ring
should be changed.
Loading the Sample into the STA 6000
NOTE: Good quality data require uniform thermal contact between the pan and the support.
Avoid spilling sample materials into the support.
Use the following procedure to load samples or remove samples:
1. Using tweezers, remove the stainless steel cover from the top of the analyzer.
Place it on the stainless steel ring surrounding the opening to the furnace.
2. Place the sample inside the sample pan.
3. With tweezers, carefully place the sample pan with sample onto the sample holder and
make sure that the pan is centered.
4. Replace the cover.
CAUTION
ATTENTION
Take exceptional care not to drop sample pans or sample material into
the furnace. If this should happen, stop the experiment immediately and
cool the furnace.
Prenez des soins exceptionnels pour ne pas laisser tomber les poêles
d'échantillons ou les échantillons dans le four. Si cela se produit, arrêtez
l'expérience immédiatement et refroidissez le four.
