• Recent changes made to the system
• Loose connections in the detector or its signal path
• Detector contamination
• Contaminated carrier gas
If the carrier gas tank was recently replaced, re-connect the previous tank to see if the
noise decreases. If the new carrier gas is contaminated such that it saturates a trap,
changing to the old tank may show little improvement until the traps are replaced or
regenerated. This problem is most common with nitrogen carrier gas.
Noise gradually increases to an unacceptable level.
• This symptom indicates gradual buildup of the noise source, rather than an abrupt
change as described above. If the cause of the noise is not found, contact
INFICON.
11.2.1.1.4 Baseline Spiking
Spikes are isolated baseline disturbances and usually appear as sudden large upscale
movements. If these spikes are accompanied by noise, address the noise problem
first, as this may correct the spiking issue as well.
If spikes appear when a run is in progress, the cause is almost always electronic in
origin.
Loose connections are often the most likely cause of spikes. Check all accessible
cable connections.
External interference from local radio transmission equipment can also cause baseline
spiking.
