8. Analytical Quality Assurance (AQA)
The AQA interval, n measurements, is only effective if
the n measurements setting is active for the AQA mode
function.
The AQA2 check starts the monitoring for one method
at a time.
The specified number of measurements
applies to:
l
the instrument with AQA1 (total number of measure-
ments performed, independent of whether AQA2 is
active for some parameters)
l
each method an AQA check will then be performed
for with AQA2.
Thus, it is possible to define individual numbers of
measurements for different methods.
The measurements are counted separately for each
monitored method.
The monitoring intervals of AQA2 monitoring processes
already started for other methods are not affected by
changing the number of measurements. Thus the
number of measurements can be set for further
methods no matter which monitoring processes were
started before.
When an AQA2 check is performed, the
number of measurements last set in the AQA
intervals
menu is automatically taken over.
Therefore, you should check and, if necessary,
change the currently set number of measure-
ments before each AQA2 check.
The currently set number of measurements for
the AQA2 check is saved for the active method
and output in the report individually (section
8.3.4).
