Problem Probable Cause Solution
Dirty injector liner. Clean or replace.
Column has active sites. Equilibrate or replace.
Chromatographic peaks

Sample overloading the
column. Use a split injection or a smaller
sample.

Discrimination of relative
peak intensities. Poor resolution or improper
tuning. Retune.
Unstable filament. Replace filament.
Poor calibration. Recalibrate.
Air leaks at detector. Check He/Air ratio.
Peaks are flat-topped. Signal strength exceeds
dynamic range of detector. Reduce multiplier voltage.
Sample is too strong. Dilute or split.
