Note that the Page 2 parameters are only used if Both is selected
for the Inj Pos parameter.
If the operator chooses to use an Injector Position or Both, the carrousel
will not advance. Priority Sample does not support dual mode but does
support duplicate mode. (When two injections are performed from a
single vial into both injectors, that operation is referred to as "duplicate
mode".) There will be no cleaning steps between injections. All listed
parameters work as described above for Single Method and Method
Sequence Automation.

Method Parameters

The fundamental CP-8400/8410 method has three pages of parameters
that represent the most frequently used parameters and four pages of
softkeys to access more advanced features; however, predefined modes
of operation limit the need to access all parameters. Varian has
extensively researched the injection process for a wide variety of
solvents and techniques. The CP-8400 is preprogrammed with five
injection modes designed to optimize your analysis for volatile samples
(Volatile), viscous samples (Viscous), neat samples (Neat), and standard
(or generic) samples using either a split/splitless injection or an on-
column injection (Standard Split/Splitless or Standard On-Column).
Choosing one of these five injection modes will preset critical parameters
for optimum performance and limit the parameters you need to set. If you
prefer to develop your own injection method for your CP-8400/8410, the
sixth CP-8400/8410 operation mode user defined (User), allows access
to the full suite of CP-8400/8410 parameters. You should exercise care
when using the user defined mode since choices for some parameters
may have unintended consequences. An example of this is the use of an
Internal Standard with sample fill strokes. If an Internal Standard is
withdrawn and then sample fill strokes are executed, the Internal
Standard will be introduced into the sample and diluted.
