10.2.2 Questionable Chromatographic Output
Problem
Cause
Corrective action
Incorrect readings
Peaks have shifted,
integration parameters
incorrect
Check that helium pressure is at 60
psig, and / or adjust retention times.
Examine the chromatogram and
determine if peaks have shifted or if
integration parameters are not
correct.
Analyzer reads 0.000
Analyzer is Halted or
retention times have
shifted.
Check
Analysis Control
to see if the
analyzer is halted. Check the
chromatogram to see if there is a
problem with the integration of peaks.
Wrong Nitrogen/Methane
readings
Poor Nitrogen/Methane
separation
Check the chromatogram to see if the
nitrogen/methane peak separation
and integration parameters are
correct. Check all fittings inside and
outside the oven.
Two peaks observed in
chromatogram immediately
following a valve switch
event.
The valve is leaking
because it is dirty.
Disassemble the valve (see Section
15), and clean the valve.
Alternatively, a new clean valve can
be installed, and the dirty valve can
be sent back to Galvanic Applied
Sciences Inc. for cleaning.
Large unidentifiable peak. Possible contamination
Clean all tubing and solenoids with
Isopropyl Alcohol and let dry
completely. If problem persists and is
negatively affecting results, contact
Galvanic for assistance.
