This appendix contains practical method examples that can
be applied in typical situations. The examples cover three different
topic groups:
-
Watch instructions
-
Messages
-
Quality control
Watch instructions
allow the progress of a method run to be determined by the events
during the method run, for example start collecting fractions when
the first peak elutes, or equilibrate the column until the eluent
conductivity has reached a given value. This is facilitated by the Watch instructions.
The system strategy includes Watch instructions
for each monitor defined in the system. These instructions are used
to survey method runs, and instruct the system to call a specified
block or an instruction when a particular monitor signal meets a given
condition. As long as the condition is not met, the block is not
activated.
Messages can be used
in a method to provide information to the operator but also for
interaction between the system and the operator.
A Quality control procedure
in a method can be used to ensure that the quality of the results
remain consistent in a series of runs.
