RESULT CONFIDENCE IS MARGINAL/RESULT CONFIDENCE IS POOR
Descripon
LightLab may indicate that the resulting fit was marginal, and that accuracy may be
degraded or that the fit was poor and no results will display. The LightLab analyzes the
quality of the results calculated, and if the quality of the fit is not good, an error will be
returned. Marginal fit means there could be something wrong, and that the results
should not be trusted for critical applications. Poor fit means there is definitely
something wrong and the sample must be re-run.
Causes and Fixes:
1. Selective Separation Column is not installed. Install the column and re-run the
test.
2. The instrument may have been disturbed during sampling. If this is the case,
simply re-analyze the sample. The sample need not be re-extracted, there should
be enough extracted sample to re-inject the same sample again.
3. The solvent has run out. Replace the solvent by going to Settings Replace
Solvent, and then re-run the test.
