Corrective Action
Possible Cause
Symptom
1. Optimize the probe. Refer to the
ion source
Operator Guide
.
2. Confirm that the sample was
prepared correctly.
3. Verify that the fittings are the
right size and type and make sure
that they are tight. Do not
overtighten the fittings. Replace
the fittings if leaks continue.
4. Install and optimize an alternate
ion source.
5. Contact an FSE if the issue
persists.
1. The probe is not optimized.
2. The sample was not prepared
correctly or the sample has
degraded.
3. The sample inlet fittings are
leaking.
The mass spectrometer performance
has degraded.
Turn the corona discharge needle
toward the curtain plate, and away
from the stream of heater gas. Refer
to the ion source
Operator Guide
.
The position of the corona discharge
needle is incorrect.
Arcing or sparks occur.
1. Check the CDS connections.
2. Inspect the calibrant tubing for
blockages.
1. The CDS is not connected.
2. The CDS tubing is blocked.
Calibrant signal is low.
