The results obtained for one
or more properties are
unexpected / unacceptable
(continued)
Incorrect reference spectrum
selected for a spectral-subtraction
method
Check the reference spectrum that
was used. If required, reprocess
the results using the correct
reference spectrum
Incorrect fuel calibration used
(Synthetic Oil or Mineral Oil
methods)
Check the fuel calibration and, if
required, reprocess results
Incorrect Dilution Factor used
Check the Dilution Factor entered
and, if required, reprocess the
results
No results obtained for the
sample / Cell Fill Check fails
Air was aspirated with sample
(using fixed heights, actual
height of sample in container
was slightly different from
sampling height in the software)
Check the sampling heights on the
Autosampler Setup dialog, and in
the Samples screen (if specified)
against the actual sample heights
Air is leaking into the system
Check the system for leaks,
particularly between the injection
station and the lower port of the flow
cell
Sample is outside viscosity range
supported by the system
Check the viscosity of the sample
Thresholds for the Cell Fill Check
are not appropriate for the
sample
Check the scan range and the
threshold defined for the Cell Fill
Check on the Batch Options dialog
