number of plunger strokes to reduce the chance of an air pocket in your syringe.
Typical values are between 3 and 10.
g. Air and filling mode—Choose Auto to use the default or Custom to change the
parameters.
h. Sample Viscosity—Select Viscous if your sample is viscous or Non Viscous if your
sample is non-viscous. With a viscous sample, the syringe is filled more slowly than if
it was non-viscous. Since the amount of time saved is so small, setting this option to
Yes might be easier.
i. Sampling Depth in Vial—Select the Bottom Sense check box and enter the height
from the bottom of the vial (in mm) at which the tip of the syringe needle will be
placed in the sample vial when it is being filled.
j. Injection Depth—Select Standard or Minimum to indicate how the sample is
introduced into the GC. If you select Standard, the autosampler inserts the needle all
the way into the injection port. If you select Minimum, the autosampler barely enters
the injection port.
k. Pre-inj Dwell Time(s)—Use this field to enter the time (in seconds) that the needle
will be in the injection port before the plunger injects the sample.
l. Post-inj Dwell Time(s)—Use this field to enter the time (in seconds) that the needle
will be in the injection port after the plunger injects the sample.
6. Configure the settings under the Washes tab (see Figure 49 ):
