Chromatographic Symptoms

Troubleshooting and Maintenance Guide

Poor sensitivity

•

Incorrect tuning

•

Tune file that does not match the type of analysis

•

Repeller voltage is too low

•

Incorrect temperatures (column, GC/MSD interface, ion
source, or mass filter)

•

Incorrect sample concentration

•

Leaking GC inlet*

•

Dirty GC inlet

•

Incorrect split ratio

•

Purge off time in splitless mode is too short

•

Excessive pressure in the MSD

•

Dirty ion source

•

Air leak

•

Poor filament operation

•

Detector (HED electron multiplier) is not working correctly

•

Incorrect mass filter polarity

* This could cause a fault condition in the GC that would prevent

the GC from operating.
