5. Peak is too small (or the sensitivity is too low.)
Cause Countermeasures
The carrier gas is leaking. Check for gas leakage and correct any piping joints
from which gas is leaking.
The split ratio is too large. (in case of split analysis) Reduce the split ratio.
The quantity of the sample injected is too small, or the
sample concentration is too low.
Increase quantity or concentration of injected sample.
The value of range or attenuation is inappropriate. Set the range larger or rise the attenuation.
The capillary column is located at a wrong place. Mount the column at the correct location. (Refer to “3.6
Mounting the Column”.)
An incorrect column is used. Replace the column to the correct one, taking the
polarity into consideration.
