Unbalanced Diodes
Not Enough Light
Too Much Light
The amount of light falling on the light receiving diodes is too high to generate
a refractive index signal.
Probable cause Suggested actions
1 The diode balance value is outside the
pre-set range -0.5 to + 0.5, an unequal
amount of light is falling on the two light
receiving diodes.
• Flush the reference cell with the mobile
phase being used.
• Perform the RID Optical Balance procedure
(see “The Optical Balance Procedure” on
page 124).
Probable cause Suggested actions
1 There is insufficient light falling on the light
receiving diodes to generate a refractive
index signal.
Flush the flow cell with the mobile phase being
used to ensure that it is free of air bubbles or
other contamination.
Probable cause Suggested actions
1 The sample cell content is varying too much
from the reference cell.
Purge reference and sample cell.
