11.2.1.3.4.2 Peak Tailing
The peak rises sharply, then falls normally to baseline.
Tailing is usually caused by column overload. Reduce the sample
Inject (ms)
time. If
using a variable volume or fixed volume injector, do not reduce the
Inject (ms)
time to
less than 15 ms to avoid repeatability issues.
Tailing could also result from two (or more) closely unresolved peaks. Decrease the
column temperature by 30°C and repeat the analysis. If peaks separate at the lower
temperature, the tailing was caused by unresolved peaks.
Tailing can also be caused by a low
Sample Inlet Heater Temperature
. Increase the
Sample Inlet Heater Temperature
and repeat the analysis.
11.2.1.3.4.3 Deformed Peak Apex
Top (apex) of the peak is deformed or flat.
A deformed peak apex is usually caused by detector saturation. Reduce the sample
Inject (ms)
time. If using a variable volume or fixed volume injector, do not reduce the
Inject (ms)
time to less than 15 ms to avoid repeatability issues.
A deformed peak apex can also result from a detector
Sensitivity
set to
High
. Ensure
that the
Sensitivity
is set to
Standard
. Sensitivity setting is not applicable for the FAST
Enabled Micro GC Fusion.
