Operation of the Double Furnace Solids Module
Preparing for the measurement
IMPORTANT
Oxygen (4.5) must be used as carrier gas when using the Double Furnace Solids Module.
Switch on the analyzer as follows:
1.
Before switching on the analyzer check that the solids module has been tightly installed
and connected as specified.
2.
Switch on the analyzer.
The carrier gas flow is automatically adjusted to 400 ml/min.
3.
Carry out the system leak test (see section "Checking the system for tightness" in the
operating manual of the analyzer).
4.
Heat up the combustion furnace. To do so set the furnace temperature in the window
Options / tab Device components to the desired temperature (e.g. 900 °C).
Tempering the sample boats
IMPORTANT
The sample boats might be contaminated. Temper the sample boats prior to analyzing
standards and samples. Tempering is performed by an "empty measurement".
After tempering do not touch the sample boat by hand any more. Use e.g. a clean petri dish
to store the sample boats and a clean pair of tweezers to transport them.
Performing the analysis
Note:
When using the solids module only measurements with manual sample feed are possible.
Prepare the analysis and start the measurement as follows:
1.
Using the menu command Method / New create a new method or load an existing
method.
To do so open via the menu command Method / Load the database window Method
selection, highlight the desired method and confirm the selection by clicking the button
[OK].
Note:
When creating a new method the option Horizontal furnace must be selected.
2.
In the window System state select the manual sample supply by clicking the button
[manual].
This is followed by the initialization of the analyzer.
3.
In the window System state check the following entries:
−
−
−
Note:
If one of the entries is incorrect (shown in red), carry out a fault finding exercise in ac-
cordance with the notes in the section "Fault removal" in the operating manual of the
analyzer.
