4.4 Check Samples
4.4.1 Check Sample
This refers to the empty check sample cell which is filled with a local sample and
used together with prediction models suitable for that sample type. For info about the
artificial FOSS Check Sample please see section 4.4.2 FOSS Check Sample.
A Check Sample (or Control Sample) is measured on a regular basis to validate the
stability of the analyzer and everything around it that affects its performance
(environment etc.). Frequency for the test is determined by your local quality
routines but a daily check sample test is the normal recommendation.
The local check sample is a real sample and as such it will not last forever. It will dry
out or in other ways change its properties over time. The check sample needs
therefore to be replaced on a regular basis and this frequency can either be
determined in advance (based on experience with your samples) or monitored in
ISIscan Nova by looking at how the results for the check sample changes.
Replacing the check sample with a new sample will most likely change the measured
result(s) for it and therefore the targets for the check sample test must be changed
accordingly. This can be done manually in FossManager or via a new check sample
definition in ISIscan Nova.
