Sampling Parameters
Parameter
Description
Sample Volume
Enter a value for the injection volume. The range depends on the
size of syringe selected in the Instrument Configuration. For a 5 μl
syringe the range is 0.0-2.5 μl and for a 10 μl syringe, 0.0-5.0 μl.
Plunger Strokes
Select the number of strokes of the plunger used to eliminate air
bubbles. The range is 1-15.
Viscous Sample
Select the check box to indicate that the sample is viscous. Clearing
the check box implements a fast aspiration speed while a selected
check box leads to a slow one.
Sampling Depth
Choose the position of the needle in the vial from which the
aliquot is drawn. The options are
Bottom
or
Center
.

Injection Depth
Choose an injection depth. The options are
Standard
or
Minimum
. If the pre and post -injection dwell times are set to
zero, the autosampler defaults to the
Minimum
