Operation
Default Clean Vial (I, II, III) – This parameter specifies the wash solvent
vial that will be used by the Default Cleaning procedure. The default
value is 1.
Default Clean Volume (0-5, 0-10, or 0-100 µL) – This parameter defines
the amount of cleaning solvent that will be drawn up and expelled to
waste. The volume is selectable in 0.1 µL increments for the 5 and 10 µL
syringes. The default value is 5.0 µL.
Number of Clean Strokes (0-10) – This defines the number of times the
cleaning solvent will be drawn up and expelled into the waste cup. The
default value is 1.
Default Clean Drawup Speed (0.1-25, 0.1-50, or 1-100 µL/sec) – This
parameter specifies how quickly the plunger will be withdrawn from the
syringe drawing solvent into the barrel. The default value is 5 µL/sec.
This same value should be used as the plunger speed when expelling
the syringe contents into the waste cup.
Page 2 Parameters and Softkeys
Air Plug After Sample (0-5, 0-10, or 0-100 µL) – This parameter defines
the volume of air drawn up after the sample has been drawn into the
syringe. The valid range is selectable in 0.1 µL steps for the 5 µL and 10
µL syringes. The default value is 1 µL.
Sample Air Gap (Yes or No) – Setting this parameter to Yes will cause
the syringe plunger to be withdrawn an amount corresponding to 1 µL
prior to the syringe sled descending and the sample being drawn up.
Setting this parameter to No will cause no upper air gap to be formed.
The default value is No.
Number of Fill Strokes (0-99) – This parameter defines how many
times the syringe plunger will be "pumped" (withdrawn and then
advanced). This parameter is required to effectively flush the syringe with
the sample to remove bubbles and prevent dilution of the sample by
residual solvent from wash processes. The syringe will use the Plunger
speed parameters as defined in the viscosity settings page. The default
value is 0.
Fill Volume for Fill Strokes (0-5, 0-10, or 0-100 µL) ) – This parameter
defines the volume that will be used by the fill strokes specified above.
This volume will usually be equal to or larger than the sample volume
specified in the SampleList. The default value is 5 µL.
