QC sample (Yes/

Quality control (QC) samples are used as a means of studying the
variation within and between batches of a particular analysis. A typical
QC sample will be stable, homogenous, typical in composition to the
types of sample normally examined. The concentration of a QC sam-
ple is known accurately and its composition is as close as possible to
one of the samples to be analysed.
Quality control samples can be used for a measurement or a titration
method.
Select Yes for QC sample if you wish to perform measurements on
QC samples.
The QC sample ID, the periodicity of QC samples and the minimum
and maximum acceptance limits for the control test are entered in the
QC data menu.
If the QC test fails, the method can be locked, so that it is impossible
to run the method while the QC sample results lie outside the preset
limits.
