Problem Probable Cause Solution
Solvent tailing. Inadequate splitter flow. Increase the splitter flow.
Column not properly
installed in the injector. Reinstall the column in the
injector.
Loss of high end compounds. Temperature setting too
low on the injector,
column oven or transfer
line. Increase the injector, column
oven or transfer line
temperature to allow the less
volatile compounds of the
sample to reach the mass
spectrometer.
Peaks at masses 28 (nitrogen)
and 32 AMU (oxygen) are in a
ratio of < 4 to 1, and the peak at
mass 28 is larger than the peak
at mass 18. Leaks in or around
vacuum or column
fittings. Tighten the fittings and
connection points to the high
vacuum system.
Set the injector split flow to
50:1.
Peaks at masses 14 and 16 are
larger than the peak at mass 28. Leaks or improper tuning. Tighten the fittings and
connection points to the high
vacuum system.
Set the injector split flow to
50:1.
Run AutoTune.
