One reason could be that:
The quality of the crucible is bad. Use a better quality.
Another reason could be that:
The furnace temperature is too high, due to:
– Excessive main voltage.
– Excessive sample and / or accelerator weight.
– The use of a "sample or accelerator" that requires lower generator power.
In this case reduce the generator power.

When the analysis cycle is carried out normally and the sample is burned but no
peak on the screen, possible reasons are the following:
- The IR cell could be faulty. Check the base lines.
See chapters “Check base lines” and “Infrared cell adjustments”.
If the base lines are as described, the IR cell can be regarded as ruled out. If
the base lines are practically at zero volts, the cell is faulty or without power.
(24VDC). See chapter Bad combustion.

If the Analyzer vibrates when the main power switch is turned to position 2, the
reason is dust accumulation on the blades of the oscillator’s blower. The vibrations
are caused by dust on the blades causing eccentrical rotations.
Mortal danger from electric shock
Exposed power contacts - High Voltage
Disconnect the power before removing the oscillator lid.
