• The probe is not installed.
• The probe is not connected
securely.
• Install the probe. Refer to
Install the Probe in the Ion
Source Housing on
page 87.

Sensitivity is poor. Excess high voltage induces
fragmentation before the ions
enter the mass filters.
Optimize ISVF or DP. Refer
to Optimize the
TurboIonSpray Probe on
page 90 or Optimize the
APCI Probe on page 92.
During testing, the ion source
fails to meet specifications.
The mass spectrometer has
not passed the installation
tests.
The test solution was not
prepared correctly.
Perform installation tests on
the mass spectrometer with
the default source.
Confirm that the test
solutions were prepared
correctly.
If the problem cannot be
resolved, contact an FSE.
Background noise is high. • Temperature (TEM) is too
high.
• Gas 2 flow rate (GS2) is too
high.
• Optimize TEM.
• Optimize GS2.
