Default Settings for Predefined AutoSampler Modes
The following table lists the parameter settings used for each of the Predefined
8400/8410 modes using a 10 microliter syringe. If the predefined modes do not
work acceptably for your samples, use the User Defined mode to enter settings
that will work better with your samples. The values listed in this table provide a
starting point for setting the various parameters.

Instead of fill strokes Neat mode fills the syringe with sample at 2 uL/sec then
expels it into the waste cup at 50 uL/sec. It does this a total of six times. Then it
fills the syringe with sample at 2 uL/sec and expels it back into the sample vial at
50 uL/sec. This “pumping” action is done three times. After this is completed, the
sample is loaded into the syringe and injected using the parameters in the table.
