Problem
Possible cause
Solution
Areas and heights
are shown, but there
is no concentration
for samples.
The system has not
been calibrated.
Do a calibration and analyze the samples again.
Patterned air spikes
Time to valve is not
correct
If the air spikes occur with every peak in the same location, look
at the time for the sample to get to the valve and the load time.
Random air spikes
Dissolved gases
come out of the
solution
• Prepare reagents a day in advance and keep the reagents at
room temperature.
• Degas all reagents with helium (unless otherwise noted).
• Use a longer backpressure loop. Increase in 50 cm
increments.
• See if the air is pulled in the reagent flow intermittently.
• Make sure that there is sufficient reagent volumes.
Transmission tubing
seal to nipple is not
complete
Bad reagent
Sampler initialization
error
Sampler fails to
initialize
• Under the "Configuration" tab in the software, select
"Autosampler". Select "Initialize Autosampler".
• Make sure that the power to the sampler is on.
• Make sure that sampler cable is not loose.
• Make sure that the latest software is installed.
The computer shows
that an application
error or a runtime
error has occurred.
More than one
program operates at
the same time.
Select Ignore when asked. Close Windows
™
and start the
application again.
The standards fail
Multiple causes
• Make sure that the check standards are made and added
correctly.
• Make sure that the peaks are integrated correctly.
• Make sure that the reagent preparation and placement are
correct.
• Make sure that the time to the valve is correct.
Calibration failure
Peak integration is
not correct
Standard preparation
is not correct
Placement of sampler
is not correct
Flow/chemistry
problem
Sampler time out
Problem with sampler
arm movement
• Make sure that the sampler arm moves freely.
• Under the "Configuration" tab in the software, select
"Autosampler". Select "Initialize Autosampler".
• Look for loose or unplugged sampler cable.
Communication error
with the system
The heater element
does not get warm.
Heater temperature is
not set correctly.
• Make sure that the heater temperature has been set for that
channel in Run Properties>Analytes. Make sure that the set
point shows correctly in the Omnion channel data display.
• Connect the thermocouple
• Contact technical support
Thermocouple is
loose or not
connected
Controller does not
work
