PlasmaQuant 9100 (Elite) Troubleshooting
53
¡ Check injector tip for deposits and
clean it
¡ Increase distance between injector
and plasma (move torch down on
height adjustment or increase auxil-
iary gas flow)
¡ Use argon humidifier or inline filter
¡ Nebulizer gas set too low ¡ Optimize carrier gas flow
¡ Adjustment on analyte channel ¡ Adjust method parameter x/y offset
in the
Spectrometer
|
Adjust plasma
view
window (see online help or
software instructions)
¡ Leak in the sample supply system
(sample and pump hoses)
¡ Check sample and pump hoses and
their plug connectors
¡ Plasma compartment windows dirty ¡ Replace windows
¡ Transparency in the UV vacuum
missing
¡ Check the duration of the purging
gas flow. Wait for the purging gas to
completely flood the spectrometer
chamber
Sensitivity too low
Cause Remedy
¡ Same fault causes and remedies as the "No signal" fault screen
Measured value too low
Cause Remedy
¡ Incorrect calibration ¡ Check calibration solutions and re-
peat calibration
¡ Low solubility substances lead to
low concentrations
¡ Low solubility substances not com-
pletely digested
¡ Optimize sample preparation
¡ Volatile substances escape during
sample preparation
¡ Optimize sample preparation
¡ Spectral interference in the calibra-
tion standard
¡ Use another analytical line
¡ Background correction fault ¡ Select background correction points
that are not spectrally disturbed
¡ Better adjustment of a curved back-
ground via non-linear correction
function
¡ Fault when using an internal stan-
dard
¡ Wrong standard dosage
¡ Internal standard concentration not
in linear range. Select lower concen-
tration for standard
¡ Insufficient reaction adjustment to
plasma temperature change. Matrix
adjustment and better fit between
the analytical line behavior and the
internal standard
¡ Contamination/carry-over in the
cal/zero solution
¡ Remedy carry-over/contamination
cause
