Operation
Controlling the XY Autosampler through Agilent ChemStation
• Pump Direction, either CW (clockwise) or CCW (counter-clockwise).
• Sample Return, which allows you to define the amount of analyte (in
percent) transferred back into the vial. The default percentage of sample
return is 0.
• Air Segment, which defines the time in seconds for which air is drawn into
the system before the sample is drawn in. The default air segment is 0 s (no
air segment).
• Wash Time, which sets the time in seconds the needle is dipped into the
rinsing well of the rinse station. This is done between consecutive sample
measurements, in order to prevent the needle from carrying over sample
from different vials.
The terms rinse station and wash station are used synonymously through
out this manual.
Manual Control of the XY Autosampler
After having set the parameters for the XY autosampler, you can advance the
probe arm and needle of the sampler by clicking on the sampler icon in the
graphical user interface and selecting a new sampler position or typing in a
vial number and pressing the enter key.
This approach is available in all three modes supporting the XY autosampler,
that is, standard, advanced and dissolution mode.
Automated Control of the XY Autosampler
General Purpose Software
The Agilent ChemStation standard mode provides you with an easy way to
setup the automation table.
You can set tasks such as:
• blank measurement(s)
• control measurements (maximum is two)
• sample measurements
• standard measurements (maximum is three and only in quantification
task)
