When you select File - New - Method - [method type] the relevant parameters and their default
values will be displayed for the selected method type. You can now adjust the parameters as
required and save the method with a name of at most 11 characters.
7.5.1 Running Method from Evolution Workstation
Once a method has been saved, you can select Method - Execute menu option to send it to the
OPTIC-4 control unit. It will start the method run on OPTIC-4. If you use manual injection, wait for
OPTIC-4 to enter the Waiting for Run In state, then inject the sample and select Method – Run
menu option or press RUN button on the local interface. The Evolution Workstation status graph will
start displaying the instrument parameters when the run state changes to Running.
Note:
In order to prevent unintended method interruption, it is recommended to disable
the PC sleep mode. Please, refer to Power Options with the Windows’ Control Panel
on how to disable the sleep mode.
7.5.2 Stopping Method from Evolution Workstation
While the Instrument is in the Initialize Method, Waiting for Ready In, Equilibrating or Waiting for
Run In state the method can be stopped by selecting Method – Standby menu option or by pressing
button STANDBY on the local interface. The Instrument will return to the Standby state. If the
Instrument is in the Running OPTIC Method or the Running OPTIC & GC Methods state, the current
run can be ended by selecting Method - End Run menu option or by pressing button END RUN on
the local interface. The current run will be stopped; the instrument will be returned to the Initialize
Method state and a new run with the same method will be started.
7.6 Optimizing Method
Some method parameters may have to be optimized by varying a parameter value within a certain
range. The Evolution Workstation makes it possible to create a sequence of methods to perform
such an optimization. The optimization sequence is created automatically after a sequence name,
parameter to be optimized, its minimum and maximum values and a step size in the sequence are
defined.
To create an optimization sequence:
• Select Method – New Optimization Sequence.
• Enter the name of the sequence and the directory it should be stored in.
• Choose the parameter to be optimized, its minimum and maximum values and the step size.
• Select ‘OK’ to save the sequence.
The Sequence window will then be displayed where you can modify the sequence as required. For
more information about sequences you are referred to Chapter 8 “Defining and running sequences”.
