Operation
CP-8400 AutoSampler & CP-8410 AutoInjector 29
Method (Method 1 to Method 8) – This parameter selects which of the
local methods will be used for single automation. Default selection will be
Method 1.
Initial Sample (0 to 99 for the CP-8400, 1 to 21 for the CP-8410) – The
Initial Sample represents the vial position of the first vial to be used with
the specified method. The Initial Sample position must be less than or
equal to the Final Sample. Setting the Initial and Final Samples to the
same vial position will cause only that vial to be used. The default value
is 0 for the CP-8400 or 1 for the CP-8410.
Final Sample (0 to 99 for the CP-8400, 1 to 21 for the CP-8410) – The
Final Sample represents the vial position of the last vial to be used with
the specified method. The Final Sample position must be greater than or
equal to the Initial Sample position. Setting the Initial and Final Samples
to the same vial position will cause only that vial to be used. The default
value is 99 for the CP-8400 or 21 for the CP-8410.
NOTE: If either an initial sample selection or a final sample selection can
not be reached by the CP-8410 tower due to the sample tray orientation,
those vials that can not be reached are treated as missing vials.
Injections / Sample (1 to 99) – This parameter defines how many
injections will be performed from the same vial. When only a single
injector is used, this parameter application is obvious. When both
injectors are used, the application of this parameter will treat the two
injectors as one. If Advance Carrousel for Second Injection is set to Yes,
the AutoSampler is at vial position 10, and the Injections/Sample is set to
3, then the CP-8400 will inject from vial 10 followed by vial 11. After the
run finishes, the CP-8400 will again inject from vial 10 followed by vial
11. This process will be repeated a third time. If the Advance Carrousel
for Second Injection is set to No, and we are again considering the
situation in which the AutoSampler is on position 10, then the CP-8400
will inject from position 10 into both injectors. When the run ends, it will
again inject from vial 10 into both injectors. It will repeat the process a
third time. The default value is 99.
First Injection Volume (0.1 to either 5 or 10 µL or 1-100 µL syringe
depending on configured syringe) – This selection defines the volume of
sample that will be used for the first injection. If only one injector is being
used, this volume represents the volume that will be injected. Note that
there are two places where the number of injectors are set. The first
place is in Setup where you configure the instrument (if you have
selected a single injector in Setup, then this field will be labeled Injection
Volume). The second place will be in the Injector Position parameter
(described below). If the Injector Position parameter selects either
position 1 or Position 2, then the First Injection Volume will be the only
