STA 8000 Maintenance
The STA 8000 analyzer needs little routine maintenance other than giving it the proper
treatment of a sensitive electromechanical device. Avoid contamination of the furnace by
always using a system purge gas and, ideally, a sample purge gas. If the furnace should
become contaminated, clean it as soon as possible (refer to
Cleaning and Decontamination
on page 33 for more information).
When cleaning the analyzer, use the following procedures:
• Cleaning the Furnace and Sensor
• Cleaning the Cover
Cleaning the Furnace and Sensor
When the furnace and sensor have become contaminated with reaction products, the best
method of cleaning them is to heat the furnace up to 1400 °C in an air or oxygen
atmosphere for approximately 10 minutes. This should remove all products that can be
oxidized.
CAUTION
ATTENTION
Do not remove the furnace lid when heating at high temperatures.
Ne pas enlever le couvercle du four lorsqu'il chauffe à des températures
élevées.
If the sensor becomes contaminated, remove it from the furnace and clean it
gently
with a
small brush.
When a sample has dropped into the furnace, remove the sensor first, if present, and then
remove the sample material, preferably with a vacuum. Take care that material does not fall
into the hole for the sensor.
Cleaning the Cover
The reaction byproducts from the samples run inside the STA 8000 furnace and condense on
cold spots of the instrument: the bottom side of the cover and the top inner part of the
cooling jacket. The bottom side of the cover can be cleaned easily with a tissue and some
solvent. This should be done on a regular basis. The top inner side of the cooling jacket can
be cleaned in a similar manner.
