Plasma shut-down: not stable!
Cause
Remedy
−
The plasma is unstable due to the
sample matrix or entry of oxygen (leaks)
−
Adjust the plasma conditions (increase
performance)
−
Reduce the nebulizer gas flow
−
Reduce the pump speed
−
Increase the distance of the torch to the
cone; reduce the distance to the
induction coil; search for leaks in the Ar
gas line, if necessary

Firmware update communications error
Invalid checksum of firmware application!
Invalid firmware block!
Invalid firmware block sequence
Write-error firmware update
Cause
Remedy
−
The firmware update has failed
−
Repeat the firmware update
−
Inform service

Status: Plasma error!
Cause
Remedy
−
Device communication error
−
The step motor for grating, prism,
shutter is faulty
−
Restart the device (and PC if relevant)
−
Inform service

Equipment faults and analytical problems
Other problems that are not detected by system monitoring can also occur. Starting a
measurement is possible. Such errors are usually detected on the basis of implausible
measuring results (analytical problems) or are clearly visible in the equipment technology.
If the suggested solutions are not successful, inform service.
No signal
Cause
Remedy
−
The pump does not deliver any
sample
−
Check the hose / hose pump
−
The nebulizer is clogged; the
mass-flow rate is very high (in
the P
LASMA
R
EPORT
window)
If necessary, check with Na solution (1 g/L) – if no plasma coloring
(orange) is observed:
−
Check the nebulizer nozzles for obstructions and clean them
(see "Cleaning the nebulizer" p. 50)
−
If the sample nozzle is clogged
filter the solutions
−
If the argon nozzle is clogged
dilute the measurement
solutions or use an argon humidifier
−
The injector is clogged
Check with Na solution (1 g/L) – if no plasma coloring (orange) is
observed:
−
Check the injector tip for deposits and clean it
−
Increase the distance between the injector and plasma
(move the torch down on the height adjustment or increase
auxiliary gas flow)
